Answer: 1 mole Kr
Explanation: solution
83.80g Kr x 1mole Kr / 84 g Kr
= 0.997 or approximately 1 mole Kr
Answer:
the total density of the mixture = 3.415 x 10^3 g/mL
Explanation:
given:
density of a substance is 3.4 x 10^3 g/mL
Mixing it with another substance increases the density by 1.5 x 10^1 times.
find:
What is the density of the mixture?
-------------------------------------------------
let density (a) = 3.4 x 10^3 g/mL
density(b) = 1.5 x 10^1 g/mL
since there is no specific density provided for the mixture, we then add both to increase the density,
total density = density(a) + density(b)
total density = 3.4 x 10^3 g/mL + 1.5 x 10^1 g/mL
total density = 3.415 x 10^3 g/mL
therefore,
the total density of the mixture = 3.415 x 10^3 g/mL
