1) find the molar mass of C₇H₁₄O₇.

$=7(12.01)\ +\ 14(1.01)\ +\ 7(16.00)\\\\=84.07\ +\ 14.14\ +\ 112.00\\\\=210.21\ g/mol$

2) solve using dimensional analysis

$=0.159\ mol\ C_{7}H_{14}O_{7}$ × $\frac{210.21g\ C_{7}H_{14}O_{7}}{mol\ C_{7}H_{14}O_{7}}$

= 33.42339

= 33.4g C₇H₁₄O₇

This law states that, despite chemical reactions or physical transformations,
mass is conserved, that is, it cannot be created or destroyed. within an isolated system. In other words, in a chemical reaction, the mass of the products will always be equal to the mass of the reactants.
