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.
