4.0 % in mass per volume :
4.0 g ---------- 100 mL
1.2 g ---------- ( volume )
Volume = 1.2 x 100 / 4.0
Volume = 120 / 4.0
= 30 mL
hope this helps!
Answer:
No. It is more dense than the uncrushed bread.
Explanation:
The mass is the same, however the volume has been decreased on the crushed side, forcing more matter into one space, which increases the density.
Answer:
disagree it wont be the same momentum
Explanation:
cuh
Stratosphere :) hope this helped
The answer is: all true
<span>A. As the pressure of the gas increased, the volume of the gas decreased.
It is clear that if you compare the data on the left side. When the pressure increased the volume is decreased.
B. For all pairs of data of pressure and volume, P • V was appoximately the same.
The pressure is inversely related to the volume. You can take two data to prove it. Let use the first and second data
V * P= 1.03 * 50= 51.5
</span>V * P= <span>1.08 * 47.5= 51.3
C. For all pairs of data of pressure and volume, P • V mr001-1.jpg k for the same value k.
D. The regression equation was of the form V = kP–1 (which is the same as V = k/P).
The value of k can be expressed as k= P*V. If the equation is turned around, it could be expressed as V= k/P
The value of k is constant on different data, proved by the calculation on the second statement above. The value of k should be around 51.5
