Answer:
Molarity = 1 M
Explanation:
Given data:
Number of moles of NaHCO₃ = 0.1 mol
Volume of solution = 100 mL
Molarity of solution = ?
Solution:
Formula:
Molarity = number of moles of solute/ volume of solution in L
Now we will convert the mL of water into L.
100 mL × 1 L/1000 mL
0.1 L
Now we will put the values in formula.
Molarity = 0.1 mol/ 0.1 L
Molarity = 1 M
The answer to this question is that the percentage by volume of a hyrdrogen peroxide in mostly first aid kits contains 3%. Hydrogen peroxide or H2O2 is a compound that can be used as an antiseptic in orderto prevent infections from spreading in the bruises, cuts, and even burns. Hydrogen peroxide can also be used as a bleaching agent and an oxidizer.
We are given with the mass percentage of the elements. Taking a 100-gram basis, we<span> convert the mass of the reactants to moles. Hydrogen is equal to 1.6 moles , nitrogen is equal to 1.3058 and oxygen is equal to 4.7625 moles. We divide each number </span>to <span>the least amount. Hence H is 1.22, N is 1.00 and O is 3.65. Answer is HNO3, nitric acid.</span>
