Question

Can someone help me or show me how to do this problem?

" What is the mass in grams of each of the following samples?

1.505 mol of Ti? "

Thank you!!

Answer 1

first molar mass of Ti is about 47.8 gr/mol.
then we know that we have 1.505 mol of Ti.
so we use this formula \[n=\frac{ m }{M }\]n=1.505
M=47.8 gr/mol
m=? gr
\[m=1.505 \times 47.8 \approx 72\]

Answer 2

we know that \[n = \frac{ m }{ M }\] with :
' n ' in moles and ' m ' in grams and ' M ' is nbr atomique
so we have \[m = n * M = 1.505 * 47.8 = 72 g\]
