Answer:

check explaination

Explanation:

<u>Q. 4:</u>

a) 7 ml

b) 9 ml

c) volume of rock = volume of column (with rock in it) - volume of column (without rock)

= 9-7

= 2 ml

d) density = mass ÷ volume

therefore, mass = volume × density

= 2 × 3 => 6 g

<u>Q. 5:</u>

1st has the highest density

this is because, density = mass ÷ volume

as volume is constant , density is directly proportional to mass

as image 1 has more number of molecules, it's mass will be maximum.

therefore, 1st image will have maximum density

How many milliliters of a 0.266 m lino3 solution are required to make 150.0 ml of 0.075 m lino3 solution?
Allisa [31]

We need an equation that would relate the concentration of the original solution to that of the desired solution. To solve this we use the equation expressed as follows, 

M1V1 = M2V2

where M1 is the concentration of the stock solution, V1 is the volume of the stock solution, M2 is the concentration of the new solution and V2 is its volume.

M1V1 = M2V2

0.266 M x V1 = 0.075 M x 150 mL

V1 = 42.29 mL


Therefore, we need about 42.29 mL of the 0.266 M of lithium nitrate solution to make 150.0 mL of the 0.075 M lithium nitrate solution.
