9. what is the molar mass for... (nh4)2cro4

Question

Accepted Answer

# Explanation:
## Step1: Determine the atomic masses
The atomic mass of $N = 14.01\space g/mol$, $H= 1.008\space g/mol$, $Cr = 52.00\space g/mol$, $O = 16.00\space g/mol$
## Step2: Calculate the molar mass of $(NH_{4})_{2}CrO_{4}$
$$
\begin{align*}
M&=2\times(14.01 + 4\times1.008)+52.00+4\times16.00\
&=2\times(14.01 + 4.032)+52.00 + 64.00\
&=2\times18.042+52.00+64.00\
&=36.084+52.00 + 64.00\
&=152.084\space g/mol
\end{align*}
$$

# Answer:
$152.084\space g/mol$
