Answer:
55.3 M
Explanation:
Given temperature = 25°C
Density = 0.997 g/mL
Based on density the mass of water per L = 997 grams
The molar mass of water = 18
The moles of water =
The molarity is defined as the moles of water per litre.
The moles = 55.3
Volume = 1 L
So molarity = 55.3 /1 = 55.3 M
<span>magnesium oxide is a compound that is composed of one atom of magnesium and two atoms of oxygen. The compound is a combination of Mg2+ ion and O2-. The ions translate into atoms which reflects on the subscripst of the elements already. magnesium oxide is a basic oxide with the pH level greater than 7.</span>
