## How many moles are in 42 grams Na?

Answer: **0.61 moles** of Na are in 42 g of Na.

## How many moles are in sodium phosphate?

The molecular weight tells you how many grams of that element makes up one mole of that element. In Na3PO4, there are **3 Na**, 1 P, and 4 O. So the total molecular weight is 3(22.99) + 1(30.97) + 4(15.99) = 163.9 g/mol.

## How many moles of sodium are in sodium phosphate?

Sodium phosphate has **3 sodiums**, 1 phosphorus and 4 oxygens. Here if we look on the periodic table, the mass of sodium is 22.99 grams. Phosphorus is 30.97 grams and oxygen is 16 grams.

## How many moles are in sodium?

In grams, a mole is one formula mass. For example, **1 mol** of sodium (Na) has a mass of 22.9898 g (the mass on the periodic table). And 1 mol of chlorine (Cl) has a mass of 35.453 g (the mass on the periodic table).

## How many moles of Ca are there in 10 grams of CA?

∴ The Number of Moles in 10 g of Calcium (Ca)

Hence, There are **0.25 Moles** in 10 g of Calcium . . .

## How do you find moles?

Avogadro’s number is a very important relationship to remember: **1 mole = 6.022×1023** 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).

## How many moles are in 107 g of sodium?

Explanation: Na mol. mass = 23. 107g / 23 g/mol = **4.65moles** of sodium.
