a salt solution has a density of 1.15 g/mL and a volume of 0.425L. what is the mass in kg of this solution? I just need to know how to do it period
D = m/V
D is given in g/mL.
Convert volume to mL first.
V = 425 mL
D = m/V
1.15 g/mL = m/425 mL
m = 1.15 x 425 = 488.75 g =0.489 kg
To find the mass of the salt solution, you can use the formula:
Mass = Density x Volume
Given information:
Density = 1.15 g/mL
Volume = 0.425 L
First, let's convert the density unit to grams per liter (g/L):
1 g/mL = 1000 g/L
So, the density is 1.15 x 1000 = 1150 g/L
Next, substitute the given values into the formula:
Mass = 1150 g/L x 0.425 L
Now, multiply the density by the volume:
Mass = 1150 g/L x 0.425 L = 488.75 g
Finally, to convert the mass to kilograms, divide by 1000 since there are 1000 grams in a kilogram:
Mass = 488.75 g ÷ 1000 = 0.48875 kg
Therefore, the mass of the salt solution is 0.48875 kg.
