Answer:
that is the answer
Explanation:
the atoms in each side of the equation must be equal.
Molarity= moles/litres
.42M=x moles/.275litres
xmoles=.42M*.275litres= .1155 moles
molar mass of KClO3 = 122.548 grams/moles
mass= 122.548grams/moles* .1155moles= 14.15 grams of PotassiumClorate.\Hopes this loves or thanks.
Answer : The density of the block is estimated to be, .
Explanation :
Density of the water,
As we know that,
Buoyant force =
where,
g = gravitational acceleration
volume of the block = v
density of the block =
Weight of the Block = Buoyant force exerted by water
Thus, the density of the block is estimated to be, .
