Determine the mass of 2.5 cups of water if the density of water is 1.00 g/cm3 and 1 cup = 240 ml. i

Radda [10]

The mass is simply the product of volume and density. But first, let us convert the volume into cm^3 (cm^3 = mL):

volume = 2.5 cups * (240 mL/cup)

volume = 600 mL = 600cm^3

So the mass is:

mass = 600 cm^3 * (1 g / cm^3)

mass = 600g

How many grams of magnesium would be a typical amount in a 60.kg adult?

Nata [24]

Magnesium plays a vital role in the function and structure of the body.

The adult human body consist of 25 grams of magnesium i.e. 0.25 % of the human body composition approximately.

Therefore, for a 60 kg adult, then the amount of magnesium in their body would be

$0.25\times \frac{60 kg}{100}$

= 0.15 kg

Convert kg to g:

1 kg = 1000 g

So, 0.15 kg = $0.15 \times 1000$ = 150 grams

Thus, amount of magnesium in 60 kg adult is equal to 150 grams
