what is the mass of 1.00 L of ethanol? Ethanol has a density of 0.798 g/ml. (hint: one liter is 10^3 mL.)
A. 0.789 g
B. 789 g
C. 789 L
I think C
nope. First off, 789L is not a mass.
keep track of the units. You want g, and
g = g/ml * ml
.798g/ml * 1.0L * 1000mL/L= 798 g
Answer B, assuming a typo.
To determine the mass of 1.00 L of ethanol, you need to use the information given about its density. You have been provided with the density of ethanol, which is 0.798 g/mL.
To find the mass, you can use the formula:
Mass = Density x Volume
Given that the volume is 1.00 L, you need to convert it to milliliters (mL) since the density is given in g/mL.
Since one liter is equal to 10^3 mL, you can multiply the volume (1.00 L) by 10^3 to convert it to mL:
1.00 L x 10^3 mL/L = 1000 mL
Now that you have the volume in mL, you can calculate the mass:
Mass = 0.798 g/mL x 1000 mL = 798 g
Therefore, the mass of 1.00 L of ethanol is 798 g.
So, the correct answer is B. 789 g.
