Density = m/v  therefore    v = m/d     v = 25/0.85    v = 29.4117... cm^3 ( = 2.94 * 10^-5 m^3

Answer:

Q.1

Given-

Volume of solution-1 L

Molarity of solution -6M

to find gms of AgNO3-?

Molarity = number of moles of solute/volume of solution in litre

number of moles of solute = 6×1= 6moles

one moles of AgNO3 weighs 169.87 g

so mass of 6 moles of AgNO3 = 169.87×6=1019.22

so you need 1019.22 g of AgNO3 to make 1.0 L of a 6.0 M solution

Why is photosynthesis an endothermic reaction?
diamong [38]

Answer: Option (c) is the correct answer.

Explanation:

Photosynthesis is a process in which sunlight, carbon dioxide, and water is used by the plants to make their on food.  

Plants absorb energy in the form of heat from the sunlight and thus produce glucose and oxygen from carbon dioxide and water. This absorbed energy is then used to start various chemical and biochemical reactions in the plants.

Hence, photosynthesis is an endothermic reaction.

Thus, we can conclude that a large amount of energy is required to activate the reaction.
