The density is the ratio between mass and volume. So the mass is the product between density and volume. But! You have to control the units of measure.
7.85 g/l = 0.00785 kg/l
41.25 ml = 0.04125 l
Mass = (0.00785) x (0.04125) = 0,00032381 kg ---> 0,32381 g

Answer:
The correct answer is C) Driving cars gives off gases that trap heat in the atmosphere.
Answer:
The acceleration of gravity on the moon’s surface is about 1.62 m/s^2. The weight of 70N there indicates a mass of (70N / 1.62 m/s^2) = about 43.2 kilograms.
The acceleration of gravity on the Earth’s surface is about 9.81 m/s^2. That same mass here would weigh (43.2 kg x 9.81 m/s^2) = about 423.9 N.
The weight on Earth is about (423.9 / 70) =6.06 times the weight on the moon.
That’s because the acceleration of gravity on Earth is about (9.81 / 1.62) = 6.06 times the acceleration of gravity on the moon.
