You asked: How many grams are in a mole of Na2SO4?

How many grams are there in 3 moles of Na2SO4?

There are 3 moles in 458 grams of Na2SO4.

How do you find the molar mass of Na2SO4?

Using the formula and the atomic masses of the constituent elements, we can calculate the molar mass of sodium sulphate. Therefore, the formula of sodium sulphate is Na2SO4and its molar mass is 142g/mol.

How many moles of Na2SO4 make from 4 moles of h2so4?

The ratio of H2SO4 produced to Na2SO4 used is 1:1, so 0.0056 moles Na2SO4 x 1mole H2SO4/1mole Na2SO4 = 0.056 moles H2SO4.

How many grams of NaOH are in 3 moles of NaOH?

A 3.0 M solution of NaOH has 3.0 moles of NaOH per liter of solution. 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 of NaOH are in 8.00 g?

The answer is 39.99711.

How do you find the moles of NaOH?

Step 1: Calculate the amount of sodium hydroxide in moles

  1. Amount of solute in mol = concentration in mol/dm 3 × volume in dm 3
  2. Amount of sodium hydroxide = 0.100 × 0.0250.
  3. = 0.00250 mol.
  4. The balanced equation is: NaOH(aq) + HCl(aq) → NaCl(aq) + H 2O(l)
  5. So the mole ratio NaOH:HCl is 1:1.

What is gram mole?

(Often called gram-molecular weight.) A mass of a substance in grams numerically equal to its molecular weight. Example: A gram-mole of salt (NaCl) is 58.44 grams.

Why do we convert moles to grams?

When substances react, they do so in simple ratios of moles. … Balances DO NOT give readings in moles. So the problem is that, when we compare amounts of one substance to another using moles, we must convert from grams, since this is the information we get from balances.
