Molarity of a solution that contains 7.25 mg of calcium chloride in each milliliter.
<h3>What is molarity?</h3>
Molar concentration (also known as molarity, quantity concentration, or substance concentration) is a measure of the concentration of a chemical species in a solution, specifically of a solute, in terms of amount of substance per unit volume of solution. The most often used unit for molarity in chemistry is the number of moles per liter, denoted by the unit symbol mol/L or mol/dm3 in SI units. A solution with a concentration of 1 mol/L is referred to as 1 molar, or 1 M.

The answer in this question is 4. The required hydrogen (H2) to complete the reduction of 1 mole of (3E,5Z)-3-methylhepta-3,5-dien-1-yne is 4 hydrogen. The number of hydrogen that is require is 4 to complete reduction of 1 mole. Hydrogen is defined as a chemical element with chemical symbol of H and an atonic number of 1, described by the scientist as the most abundant element in the universe.
Some of the negative consequences of cobalt mining are pollution and child trafficking.
<h3>Effects of cobalt mining</h3>
Many young children are made to work in mines generally either due to continued struggle for survival or forced into it by child traffickers.
Apart from that, cobalt mining causes pollution in the environment. Inhalation of dust containing cobalt causes a host of health issues such as lung cancer and damage to human skin.
Other effects include soil degradation and pollution, water pollution due to mine run-offs, etc.
