Answer : The weight of water is 9 g
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to its molecular mass and contains avogadro's number 
of particles.
To calculate the number of moles, we use the equation:
1 mole of water 
weighs = 18 g
0.5 moles of water weighs = 
Thus the weight of water is 9 g
Answer:

Explanation:
hope this is able to help you :)
0.115 M means that 0.115 moles of KBr are contained in a volume of 1000 ml, therefore a volume of 350 ml will have (0.115 × 0.35) = 04025 moles
From the formula of molarity moles = molarity × volume in liters
1 mole of KBr is equivalent to 119 g
Therefore, the mass = 0.04025 × 119 g = 4.79 g
