Answer:
C) 16.3 ml
Explanation:
Density is equal to the ratio between the mass of an object and its volume:
where
m is the mass
V is the volume
In our problem, we know:
- density of aluminium:
- mass of the aluminium foil:
So we can re-arrange the equation above and use these data to find the volume of the piece of aluminium foil:
Answer:
So a=3.844 and b=5
Explanation:
Scientific notation requests to write a number using powers of ten as a factor accompanying a real number (a) between 1 and smaller than 10 that contains the digits to exactly represent the original number. So in this case, the number 384,400 can be written as:
with a=3.844, and "5" as the exponent of ten (so b=5)
