Question

In the following unbalanced equation, the molar mass of the product $'X'$ is ------ $g/mol.$
$($ At Wt. $Ca =40 u , B =10.8 u , O =16 u , S =32 u , \quad H =1 u )$
​​​​​​​
Round off answer to the nearest integer value.

Answer 1

The reaction is $\underset{\text{Colemanite}}{\left(\text{Ca}\right)_{\text{2}} \left(\text{B}\right)_{\text{6}} \left(\text{O}\right)_{\text{11}}}\left(\text{+4SO}\right)_{\text{2}}\left(\text{+11H}\right)_{\text{2}}\text{O} \rightarrow 2\text{Ca}\left(\right. \left(\text{HSO}\right)_{3} \left.\right)_{2}+\underset{\left(\right. M o l . m a s s = 61 .8 g m o l^{- 1} \left.\right)}{\underset{O r t h o b o r i c a c i d}{6 \left(\text{H}\right)_{3} \left(\text{BO}\right)_{3}}}$
