Answer:
C.
Step-by-step explanation:
I got it correct good luck bye!
1.0g/cm3 means that the mass of one cm3 is 1.0g
The easiest method to use is the rule of three, and let x be the mass of 10.0 cm3 of water
1g -- > 1.0 cm3
x --> 10.0 cm3
x= (10*1)/1
x=10.0 g
So the mass of 10.0 cm3 of water is 10.0g
Hope this Helps! :)
Step-by-step explanation:
1st way: 5x
2nd way: 5.x
third way: 5(x)
The correct answer would be 42.50
Work:
50 divided by 100 = .5
.5 * 15 = 7.5
50 - 7.5 = 42.50.
