Question

calculate the mass in grams in 10 moles of H2O

Answer 1

Well, H2O is 18 grams per mole.

Answer 2

i guess if you multiply it by 10 like 10X18. idk

Answer 3

i am here lol

Answer 4

Hye

Answer 5

mole= mass/Mr
mass= mole* Mr

Answer 6

@superhelp101 you are right
btw Mr is molecular mass

Answer 7

\[M_\text H=1.01[\text g /\text{mol}]\\
M_\text O=16.00[\text g /\text{mol}]\\~\\
M_{\text{H}_2\text O}=2M_\text H+M_\text O\\
\qquad\quad=(2\times1.01+16.00)[\text g /\text{mol}]\\
\qquad\quad=18.02[\text g /\text{mol}]\]

\[m=n\times M\\
\quad=10[\text{mol}]\times18.02[\text g /\text{mol}]\\
\quad=180.2[\text g]\]
