Amount of copper= mass / molar mass = 17/64=0.2656
According to the balance equation, amount of hydrogen gas : amount of copper = 1:1
Therefore amount of hydrogen gas is 1:1
Thus mass of hydrogen gas is molar mass x mol= 1 x 0.2656= 0.266g

How many grams of oxygen are required to react with 2.7 g of dihydrogen sulfide

KatRina [158]

Answer:

Mass = 3.84 g

Explanation:

Given data:

Mass of hydrogen sulfide = 2.7 g

Mass of oxygen required = ?

Solution:

Chemical equation:

2H₂S + 3O₂ → 2H₂O + 2SO₂

Number of moles of hydrogen sulfide:

Number of moles = mass/ molar mass

Number of moles = 2.7 g / 34 g/mol

Number of moles = 0.08 mol

Now we will compare the moles of hydrogen sulfide with oxygen.

H₂S : O₂

2 : 3

0.08 : 3/2 ×0.08 = 0.12 mol

Mass of oxygen;

Mass = number of moles × molar mass

Mass = 0.12 mol × 32 g/mol

Mass = 3.84 g

Commercially available aqueous nitric acid has a density of 1.42 g/mL and a concentration of 16 M. Calculate the mass percent of

luda_lava [24]

Answer:

The mass % of HNO3 in the solution is 71.0 %

Explanation:

Step 1: Data given

Density of HNO3 = 1.42 g/mL

Concentration = 16 M = 16 mol /L

Molar mass HNO3 = 63.01 g/mol

Assume the volume = 1L or 1000 mL

Step 2: Calculate mass of the solution

Mass = density * volume

Mass = 1.42 g/mL * 1000 mL

Mass = 1420 grams

Step 3: Calculate moles HNO3

Moles = molarity * volume

Moles = 16 M * 1L

Moles = 16 moles

Step 4: Calculate mass HNO3

Mass HNO3 = moles * molar mass

Mass HNO3 = 16.0 moles * 63.01 g/mol

Mass HNO3 = 1008.16 grams

Step 5: Calculate the mass percent

mass % = (1008.16 grams / 1420 grams) *100%

mass % = 71.0 %

The mass % of HNO3 in the solution is 71.0 %
