Answer:
The chemical formula of the compound is .
Explanation:
In 1 mole of there are 2 moles of phosphorus atom.
Then 3.3 moles of phosphorus will be in :
In 1 mole of there are x moles of oxygen atom.Then 1.65 moles of compound will have :
Moles of oxygen in 1.65 moles of compound = 8.20 mol
The chemical formula of the compound is .
Answer:
1.2 × 10³ L
Explanation:
Step 1: Calculate the total number of gaseous moles
n = nH₂ + nCl₂ = 100 mol + 100 mol = 200 mol
Step 2: Convert 30 °C to Kelvin
We will use the following expression.
K = °C + 273.15 = 30 + 273.15 = 303 K
Step 3: Calculate the volume of the container
We will use the ideal gas equation.
P × V = n × R × T
V = n × R × T / P
V = 200 mol × (0.0821 atm.L/mol.K) × 303 K / 4 atm = 1.2 × 10³ L
Multiply the mass by the abundance and add each. Make sure to convert the percentage into a decimal. (49.946 * .043) + (51.941 * .838) + (52.941 * .095) + (53.939 * .024) = 51.99 round up using sig figs and the answer is c. 52.00 amu
The answer is potassium magnate
