What mass of calcium carbonate is produced from 5.11<br> mol of sodium carbonate?
a_sh-v [17]

Answer:

There is 541.6 grams of calcium carbonate produced from 5.11 moles

Explanation:

Step 1: Data given

Number of moles of sodium carbonate ( Na2CO3) = 5.11 moles

Molar mass of sodium Carbonate:

⇒ Molar mass of Sodium = 22.99 g/mole

⇒ Molar mass of Carbon = 12.01 g/mole

⇒ Molar mass of Oxygen = 16 g/mole

Molar mass of Na2CO3 = 2* 22.99 + 12.01 + 3*16 = 105.99 g/mole

Step 2: Calculate mass of 5.11 moles of sodium carbonate

mass = number of moles of sodium carbonate * Molar mass of sodium carbonate

mass = 5.11 moles * 105.99 g/moles = 541.6 grams ≈ 542 grams

There is 541.6 grams of calcium carbonate produced from 5.11 moles Na2CO3
