Answer:
The answer to your question is 97 ml
Explanation:
Data
volume = ? ml
concentration = 1.01 M LiNO₃
mass = 6.63 g
Process
1.- Calculate the molecular weight of LiNO₃
LiNO₃ = (1 x 6.94) + (1 x 14) + (16 x 3)
= 6.94 + 14 + 48
= 69 g
2.- Calculate the moles of LiNO₃
69 g ------------------ 1 mol
6.63 g --------------- x
x = (6.63 x 1) / 69
x = 0.096 moles
3.- Calculate the volume
Molarity = moles / volume
-Solve for volume
Volume = Molarity x moles
-Substitution
Volume = 1.01 x 0.096
-Result
Volume = 0.097 l or 97 ml
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, .
Answer is: It can be reshaped by a force.
Physical property can be observed and measured without any changes in molecular composition. The same substance is present before and after the change, changing the shape is physical change.
Copper reaction with acid, ignition and combination with oxygen are chemical change (chemical reaction), because new substances are formed, the atoms are rearranged and the reaction is followed by an energy change.
