Work is measured in joules. hope this helps!
Answer:
40
Explanation:
because NaOH makes 40 grams.
Answer:
300000Pa or 3×10^5 Pa
Explanation:
Since the problem involves only two parameters of volume and pressure, the formula for Boyle's law is suitably used.
Using Boyle's law
P1V1 = P2V2
P1 is the initial pressure = 1.5×10^5Pa
V1 is the initial volume = 0.08m3
P2 is the final pressure (required)
V2 is the final volume = 0.04 m3
From the formula, P2 = P1V1/V2
P2 = 1.5×10^5 × 0.08 ÷ 0.04
= 300000Pa or 3×10^5 Pa.
Answer: The density of the object will be 
g/ml.
Explanation:
Density is defined as the mass contained per unit volume.
Given : Mass of object = 7.95 grams
Volume of water displaced = volume of the object = (95.2 - 15.5) ml =79.7 ml
Putting in the values we get:
Thus density of the object will be g/ml
200 ml is 1/5 of a liter, so the answer is five times the number of moles present in the solution. 0.6 moles/0.2 liter = x moles/1.0 liter. Solving for x gives 0.2 x = 0.6 or x = 3.0 M
so the answer is c
