$\approx 164$ $~~164$

Explanation:

Trisodium phsphate looks like this:
![http://en.wikipedia.org/wiki/Trisodium_phosphate](https://d2jmvrsizmvf4x.cloudfront.net/AWvDngmjQLORIHZgZueU_th)

It has the formula $N a_{3} P O_{4}$ $Na_3PO_4$

Therefore, it has a molar mass of:

$3 \cdot N a = 3 \cdot 23 = 69$ $3*Na=3*23=69$
$1 \cdot P = 31$ $1*P=31$
$4 \cdot O = 4 \cdot 16 = 64$ $4*O=4*16=64$

$31 + 49 + 64 = 164$ $31+49+64=164$
