Answer:
138.37 gram
Step-by-step explanation:
Formula of density
density = mass/ volume
given
volume = 202 mL
density = 0.685g/mL
using these values in Formula of density
0.685g/mL = mass/ 202 mL
mass = 0.685g/mL * 202 mL = 138.37 gram
Thus, weight of liquid is 138.37 gram to the nearest hundredth.
So say you have just 49 raised to the 1/2, that is equivocal to the square root of 49, which is 7. Instead, you have 49 raised to the negative half power, so all you need to do is move that term to the denominator of its fraction. You now have 1/49^(1/2) which turns out to be 1/7
What do you need measured
I think the answer is 2.929
