How much volume (in cm^3)is gained by a person who gains 11.8 lb of our fat? Human fat has a density of 0.918 g/cm^3

Answers

Answer 1

The volume (in cm³) gained by a person who gains 11.8 lb of fat is 5830.49 cm³

What is density?

The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as

Density = mass / volume

How to convert pounds to grams

1 lb = 453.592 g

Therefore,

11.8 lb = 11.8 × 453.592

11.8 lb = 5352.3856 g

How to determine the volume Mass = 5352.3856 gDensity = 0.918 g/cm³Volume =?

Volume =  mass / density

Volume =  5352.3856 / 0.918

Volume = 5830.49 cm³

FLAG A nurse is preparing to administer morphine 0.05 mg/kg intermittent IV bolus to a newborn who weighs 3 kg. Available is morphine 0.5 mg/mL injection. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.) ​

Answers

The quantity of morphine, the nurse should administer is 0.3 ml.

What is morphine?

Morphine is a drug which comes under the pain relieving drugs.

The quantity of morphine is 0.05 mg/kg

The weight of the baby is 3 kg.

Available morphine is 0.5 mg/mL.

0.05 x 3 = 0.15 mg

then, 0.15 mg / 0.5 = 0.3

Thus, the quantity of morphine, the nurse should administer is 0.3 ml.

Determine the grams of protein in one cup of soup that has 140 kcal with 8 g of carbohydrate and 2 g of fat.

Answers

There are 22.5 grams of protein in one cup of soup that has 140 kcal with 8 g of carbohydrate and 2 g of fat.

What is the mass of a substance?

The mass of a substance is the quantity of the substance that is being measured in grams or kilograms.

To determine the energy from the 8g of carbohydrate, we have:

= 8g × 4 kcal/g (the corresponding calories of food type)

= 32 kcal

The energy from 2g of fat = 2g × 9 kcal/g

= 18 kcal

The energy from protein is calculated as:

= 140 kcal - 32 kcal - 18 kcal

= 90 kcal

The required mass of the protein in grams is:

[tex]\mathbf{= 90 \ kcal \times \dfrac{1}{4 \ kcal }}[/tex]

= 22.5 grams

Therefore, we can conclude that there are 22.5 grams of protein in one cup of soup.
