The density of ice is approximately 0.92 g/cm3 . If a block of ice has a volume of 2300 cm3, what is its mass?

Answers

Answer:

mass = 2116g

Step-by-step explanation:

given that

density = 0.92g/cm³

volume = 2300cm³

mass = ?

recall , the formulae for calculating the density of a substance = mass / volume

density = mass/ volume

mass = density x volume

mass = 0.92g/cm³ x 2300 cm³

mass = 2116g

therefore the mass of the substance is evaluated to be equals to 2116g

Answer:

2116g

Step-by-step explanation:

$(0.92 g)/(1 cm^3)$ = $(xg)/(2300cm^3)$

Multiply .92 by 2300 to get x

x = 2116

If u add 5 to me and then divide by 9,u get 3. What number amI?

Answers

You are 22. If you add 22+5 you get 27. And if you divide 27 by 9 you get 3. So it is 22

You can set of the equation (5+x)/9=3 then solve for x. multiply both sides by 9 and then subtract both sides by 5 and you'll get 22
