How do you convert 12 grams of oxygen gas to moles?

Here we are given the mass of oxygen gas as 12 grams. Molar mass = 2×16 = 32 grams. We know the formula to calculate the number of moles. = 0.375 moles.

How do you convert grams to moles?

Divide the number of grams of the compound, NaOH, by the molecular weight and as a result, the grams (g) unit cancels and all we have left is the unit mol (moles).

What is the formula to convert into mole?

A substance’s molar mass is calculated by multiplying its relative atomic mass by the molar mass constant (1 g/mol). The molar mass constant can be used to convert mass to moles. By multiplying a given mass by the molar mass, the amount of moles of the substance can be calculated.

How do you convert from Mole 12g of oxygen gas to Class 9?

(a) 12 g of oxygen gas

  1. Given mass of O 2 = m = 12g.
  2. Molar Mass of O 2 = M = 32g.
  3. Given mass of H 2 O = m = 20g.
  4. Molar Mass of H 2 O = M = 18g.

How do you convert to Class 9 moles?

Convert into mole. (a) 12 g of oxygen gas (b) 20 g of water (c) 22 g of carbon dioxide.

  1. Mass (in grams) = no. of moles x molecular mass (g/mol)
  2. (a) Molar mass of O2 = 2 x 16 = 32 g/mol. Mass = no.
  3. (b) Given mass = 20 g. Molar mass of H2O = 2 x 1 + 1 x 16.
  4. (c) Given mass = 22g. Molar mass of CO2 = 1 x 12 + 2 X 16.
