Question

Determine mass in grams of 40.0 moles of Na2CO3

Answer 1

Explanation:

and also calculate moles in 168.0 grams of HgS please can you go the work so that way i can look at the example and do it on my own thank you in advance ...

Answer 2

The mass of 40.0 moles of Na2CO3 is 4.2392 kilograms.

• Given data :

Given compound = Na2CO3 (sodium carbonate).

Given amount = 40 moles

• From extended mathematical calculations we get that the molecular weight of sodium carbonate is approximately 105.98 g/mol.

• Which means,1 mole of Na2CO3 has a mass of 105.98 grams.

• So, 40 moles of Na2CO3 has the mass of = 105.98×40 = 4239.2 grams = 4.2392 kilograms.

(Term of unit conversion 1000 grams = 1 kilogram)

So,the mass of the 40 moles of Na2CO3 is approximately 4.2392 kilograms. (Answer)
