Solubility of a compound in water can be referred to as the amount of the compound that can be dissolved in 1 L of the solvent (water) at any given temperature. Solubility of a compound can be expressed in the units of g/L or mg/L.
Given that the solubility of calcium carbonate in water = 14 mg/L
We have to calculate the volume of water that can dissolve 11 g of calcium carbonate.
Converting 11 g calcium carbonate to mg:
Volume of water that would dissolve 11000 mg calcium carbonate
= 
=785.7 L
Rounding the volume 785.7 L to two significant figures, we get 790 L water.
Therefore, we would need 790 L water to completely dissolve 11 g of calcium carbonate.

Answer:
4.22 × 10 ⁻²² mol
Explanation:
Given data:
Number of molecules of bromine = 254 molecules
Number of moles = ?
Solution:
1 mole = 6.02 × 10 ²³ molecules
254 molecules × 1 mol / 6.02 × 10 ²³ molecules
42.2 × 10 ⁻²³ mol
4.22 × 10 ⁻²² mol
Glucose has empirical formula C6H12O6. So its formula mass can be calculated from that: 12.01x6 + 1.008x12 + 16.00x6 = 72.06 + 12.096 + 96.00 = 180.156 which needs to be rounded to two decimals to get 180.16 g/mole<span>.</span>
Answer:
Balanced forces are those two forces acting in opposite directions on an object, and they are equal in size. Anytime if there is a balanced force on an object, the object stays still or it continues moving at the same speed and in the same direction is called a balanced force.
