## Is a mole equal to a gram?

Measuring Mass in Chemistry One mole (abbreviated mol) is equal to the number of atoms in 12 grams of carbon-12; this number is referred to as Avogadro’s number and has been measured as approximately 6.022 x 1023.

**What is the formula for moles?**

Use the molecular formula to find the molar mass; to obtain the number of moles, divide the mass of compound by the molar mass of the compound expressed in grams. 9.

**How many grams are in a mole of oxygen?**

15.998 grams

### What is 25 grams in moles?

So, if one mole has a mass of 18 grams, 25 grams would have a mass of 25 grams/ 18 grams per mole or 1.39 moles.

**How many moles are in 20 grams of CA?**

Answer. Avagadro’s number, which is 6.022×10 have agram weight equal to the atomic mass. As we know that in one mole of Ca, there are 6.022×10 to the 23rd atoms.

**How many moles are in 75g of CA?**

0.75 moles

0.25 Moles

**How many moles are in 10g of CA?**

0.5 mol

**How many moles are in 2.3 grams of sodium?**

(one mole means Avogadro’s no. of atoms which has a value of 6.022*10²³. 2.3 Kg means 2300 grams of Na. Since 23 grams consist of one mole atoms, 2300 grams will consist of 100 moles( unitary method).

## How many grams are in 9.8 grams of calcium?

There are 0.24 moles of calcium in 9.8 grams of calcium. Calcium’s molar mass is 40.08 g/mole.

**How many grams are in 4.5 moles of sodium fluoride?**

Conclusion: The mass of 4.5 moles of sodium fluoride is 189g.

**What is the mass of 1.50 mol C5H12?**

The molar mass of C5H12 is 72 g/mol. This is 1.5 moles, so 108 grams.

### How many grams are in C5H12?

72.14878 grams

**What is the formula mass of C5H12?**

72.15 g/mol

**How many grams are in a mole of NaOH?**

40 g/mol

This expression means that 2 moles (or 2 x 40 g = 80 g) of NaOH are dissolved in enough water to make one liter of solution.

**How many moles are in 40 grams of NaOH?**

Now take 120 grams NaOh and multiply this by 1 mol NaOH/ 40 grams NaOH. You can cancel out the grams and you have moles left. Now you do 120 x 1 / 40 and you get 3 moles of NaOH!

**What is the mass of 0.75 moles of NaOH?**

There are 0.25 L of solution (250mL…1L1000mL) , so there are 0.25L…3.0mol/L=0.75mol of NaOH. The molar mass of NaOH is 40.0 g/mol, so there are 0.75mol…40.0g/mol=30g of NaOH, 30.

## How many moles are in 400g of sodium hydroxide?

NaoH = 23 + 16 + 1 = 40u of Mole Present in 400g of NaoH is 10.

**What is the mole of NaOH?**

40 grams

**How many moles are in 4g of sodium hydroxide?**

Answer. =0.10 (approx.)
