What is the mass in grams of 5.90 mole C8H18?

Answer 1

It is 674g.

Answer 2

Is there more to this question? You're asking for numbers for two different ideas without sufficient information. A mole [mol] is the molecular wgt in grams of a given substance which you haven't specified unless I misunderstand your question.

Learn to ask questions with scrupulous accuracy. Often then, the answer will crystallize for you from that alone---ie; a properly framed question.

Answer 3

To find the mass of 5.90 moles of C8H18, you need to calculate the molar mass of C8H18. The molar mass of C8H18 (octane) is approximately 114.23 g/mol. Therefore, the mass of 5.90 moles of C8H18 is 674.70 grams (5.90 moles * 114.23 g/mol).

Answer 4

Octane or C8H18, has a molar mass of 114.23 grams per mole. 5.90 moles of the substance has a mass of 674 grams.

Answer 5

The molar weight of C8H18 is 114 g/mol. So you can find the mass by multiplying molar weight by the number of moles. 5,90x114=672,6 grams.

Answer 6

mw (molecular weight) of C =12

mw of H = 1

12(8) +12(1)=108 g

108g = 1 mol

so 5.9 moles = 108 (5.9)= 637.2 g

5.9moles of C8H18=637.2 g

Answer 7

C: 8x12=96

H: 1x18=18

96+18=114

118x5.9= 673g

Answer 8

The mass of 5,9 moles of octane is 673,957 g.
