How many grams of phosphorus are in 500.0 grams of calcium phosphide? (i need the work also)

kvv77 [185]

Answer:

$\boxed{\text{170.0 g P}}$

Explanation:

The formula of calcium nitride is Ca₃P₂.

The masses of each element are:

$\begin{array}{lrcr}\text{3Ca:} & 3 \times 40.08&=& \text{120.24 u}\\\text{2P:} & 2\times 30.97&=& \text{61.94 u}\\& \text{TOTAL} & = & \text{182.18 u}\\\end{array}$

So, there are 61.94 g of P in 182.18 g of Ca₃P₂.

In 500 g of Ca₃P₂:

$\text{Mass of P} = \text{500.0 g Ca$_{3}$P$_{2}$} \times \dfrac{\text{61.94 g P}}{\text{182.18 g Ca$_{3}$P$_{2}$}} = \text{170.0 g P}$

There are $\boxed{\textbf{170.0 g P}}$ in 500.0 g of Ca₃P₂.

Calculate the molecular mass of glucose

yan [13]

Glucose = C₆H₁₂O₆.
Atomic mass of C = 12 u
Atomic mass of H = 1 u
Atomic mass of O = 16 u
Therefore, the molecular mass of glucose
= (6 × Atomic mass of C) + (12 × Atomic mass of H) + (6 × Atomic mass of O)
= (6 × 12) + (12 × 1) + (6 × 16) u
= 72 + 12 + 96 u
= 180 u

Answer:

180 u
