## What is the mass in grams of a mole of 12C?

12 g/mol

1 mole 12C = 6.022 x 1023 atoms 12C = 12 g 12C. 12C is defined to be exactly 12 g. MM of 12C = exactly 12 g/mol.

### What is the mass of 2 moles of C?

From the above concept of mole we tell that one mole of carbon contains \[12g\] of carbon, which is the molar mass of carbon. So the amount of carbon present in \[2\] moles of carbon =\[2 \times 12{\text{ }}g = 24g\].

**What is the mass of 12C atom in Gram?**

The molar mass of C-12 is 12 g/mol. 1 mole of C-12 contains avogadro’s number of atoms. Thus, the mass of 1 C-12 atom will be 6. 023×102312=1. 9927×10−23g.

**What is the molar mass of 12C?**

particles. It follows that the molar mass of carbon 12 is exactly 12 grams per mole, M(12C) = 12 g/mol.

## What is the mass of 1 mol of C atoms?

This unit “grams/mole” is known as the “molar mass.” The mass of mole of carbon is it’s molar mass times the number of moles: (1 mole C)*(12.01 g/mole C) = 12.01 grams (the moles cancel, leaving grams).

### How many grams are in a mole of C?

12 grams

This means that the atomic mass or atomic weight (12 grams) of carbon is equal to exactly 1 mole of carbon.

**What is the mass in gram of 5 moles of C?**

Mass of carbon is 12 g for one mole. So the total mass of 5 moles of carbon gas will be 5×12=60 . So, 5 moles of carbon gas will contain 60 grams of carbon.

**What is the mass of 2 moles of co2?**

The answer is 24 g.

## What is the mass of 2 gram atoms of calcium?

80 g

Therefore, the mass of 2 gram atoms of calcium = 40×2=80 g.

### What is the molar mass of C?

12.0107 u

Carbon/Atomic mass

Each element has its own unique molar mass. For example, carbon’s molar mass is 12.011 g/mol, and magnesium’s molar mass is 24.3050 g/mol.

**What is the mass of Ca Oh 2?**

74.093 g/mol

Calcium hydroxide/Molar mass

**How many grams are in a mole of 12C?**

molecular weight of 12C or grams The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles 12C, or 24.0107 grams. Note that rounding errors may occur, so always check the results.

## What is the mass of one atom of 12C?

The mass of a single atom of carbon 12 is simply the mass of a mole of the stuff 12garms divided by Avogadro’s number (6.022×1023). that works out of 1.9927×10-23 garms. Also to know, what is the mass of 12c?

### What is the mass of 1 mole of carbon in grams?

The mass of 1 mole of C is 12 g and 1 mol has 6.022 *10^23 atoms. This means that’s 6.022*10^23 atoms of C taken together weigh 12 g. The fact that 1 amu = 1.66*10^-24 g is not mentioned in the question, it would be wrong to assume it here since it is that value, or rather 12 times of it which has to be determined.

**What is the mass of 1 atom of C in grams?**

The mass of 1 mole of C is 12 g and 1 mol has 6.022 *10^23 atoms. This means that’s 6.022*10^23 atoms of C taken together weigh 12 g. Thus the mass of 1 atom of C has to be 12/(6.022*10^23)
