Calculate the molar mass of K3PO4

julia-pushkina [17]

Answer:

Molar mass of K₃PO₄ = 212.27 g/m

Explanation:

K₃PO₄ (Potassium phosphate)

This is a ionic salt compounded of phosphate and potassium

Mass of potassium = 39.10 g/m

Mass of phosphorus = 30.97 g/m

Mass of oxygen = 16 g/m

Molar mass of K₃PO₄ = 39.10 x3 + 30.97 + 16 x4 = 212.27 g/m

At stp,a certain mass of gas occupies a volume of 790cm3. find the temperature at which the gas occupies 1000cm3 amd has a press

Luden [163]

The temperature : 332.75 K

<h3>Further explanation</h3>

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.

volume of gas = 790 cm³ = 0.79 L

mol of gas at STP :

$\tt \dfrac{0.79}{22.4}=0.035$

Use ideal gas :

$\tt PV=nRT$

P=726 mmHg=0.955 atm

V= 1000 cm³ = 1 L

$\tt T=\dfrac{PV}{nR}\\\\T=\dfrac{0.955\times 1}{0.035\times 0.082}\\\\T=332.75~K$
