Answer:Specific gravity, also called relative density, is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume.
Explanation:
40 g glucose
Explanation:
I have to assume that you are asking about a 2% m/v solution ( Note that specifying 2% in isolation has no meaning )
2% m/v glucose solution is : 2 g glucose in 100 mL solution
Which is ( multiply by 10): 2% m/v = 20 g glucose in 1000 mL ( = 1.0 L) solution
And so 2%m/v = 40 g glucose in 2000 mL or 2.0 L solution
Answer: 40 g glucose.
Answer:
Increases
Explanation:
When a catalyst is added to hydrogen peroxide,the rate of decomposition Increases.
In living organisms, hydrogen peroxide is gotten through metabolism and it has to be broken down. This is because it could become toxic if it gets to be concentrated.
We can increase the rate of decomposition reaction through the addition of a catalyst. This breaks it down into hydrogen and water
