Density is the amount of mass in a certain volume. Density is recorded in units of grams per milliliter (g/mL). What is the density of an object is its mass 100g and its volume is 50mL?

a 0.5 g/mL
b 2 g/mL
c 50 g/mL
d 5,000 g/mL

Density = mass/volume

Density = 100g/50mL

Density = 2g/mL, so b is correct

Let me know if this helps!

b. 2 g/ml

Step-by-step explanation:

As we know density is defined as mass per unit volume so here

Density is recorded in units of grams per milliliter

So Now

Mass (m) = 100 g

Volume (V) = 50 ml

Density (d)

= m/v

= 100 / 50

= 2 g /ml

Hope it will help :)

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
