Answer: 0.0257 moles of 
and 0.0257 moles of 
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
moles of 
The balanced reaction for dissociation will be:
According to stoichiometry:
1 mole of 
gives 1 mole of and 1 mole of
Thus there will be 0.0257 moles of and 0.0257 moles of
Answer:
= 100u. Hence 10 g = 0.1 mole. Hope it's helpful to u
Magnesium silicate is a compound of magnesium oxide and silicon. It is the magnesium salt of silicic acid containing an unspecified amount of water. The molecular formula can be expressed more clearly as MgSiO3.
I’m not sure if there was important information in the question before this one, but the answer based on the info I have is B.
The density of water is 1kg/L. Since the density of the block is less, it will float.
