Which equation agrees with the ideal gas law?

Pavel [41]

The equation for ideal gas law is written as PV = nRT.

<h3>What is Ideal gas law?</h3>

Ideal gas law states that, the volume of a given amount of gas is directly proportional to the number on moles of gas, directly proportional to the temperature and inversely proportional to the pressure.

PV = nRT

where;

P is pressure of the gas
V is volume of the gas
n is number of moles
R is ideal gas constant
T is temperature

Thus, the equation for ideal gas law is written as PV = nRT.

Ascorbic acid, of vitamin c (c6h8o6), is an essential vitamin. it cannot be stored by the body and must be present in the diet.

Inessa [10]

Molecular formula of ascorbic acid is $C_{6}H_{8}O_{6}$

Molar mass of ascorbic acid = $(6 * 12 g/mol) + (8 * 1 g/mol) + (6 * 16 g/mol) = 176 g/mol$

Converting 500.0 mg of ascorbic acid to moles: We use molar mass of ascorbic acid to convert mass to moles.

$500.0 mg * \frac{1 g}{1000 g} *\frac{1 mol}{176 g} = 0.00284 mol$

Converting 500.0 mg of ascorbic acid to molecules: The conversion factor used is 1 mole = $6.022*10^{23} molecules$

$500.0 mg * \frac{1 g}{1000 mg}*\frac{1 mol}{176 g} * \frac{6.022*10^{23}molecules}{1 mol} = 1.71 * 10^{21} molecules$
