There are 1 ml in 1 gr.
NO.
The question, as stated, cannot be answered sensibly. A millilitre is a measure of volume, with dimensions [L3]. A gram is a measure of mass, with dimensions [M]. The two measure different things and basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.
As a simple mental exercise consider a ml of air and of water. They will have very different masses.
1 ml of water is 1 gram.
The given is 18gr per 90 mL so that's 1 gram per (90/18) mL or 1 gr per 5mL There is 1000 mL per one L so it's 1 gr per .005 L
This cannot be sensibly answered. A milliliter (mL or ml) is a measure of volume, grams is a measure of weight or mass.
If it's water, then it's 1 gr since water's density is 1 gr/ml. For anything else you need the density since grams are a weight metric while milliliter is a volume metric ... it would be like asking how many pounds in a gallon.
This cannot be sensibly answered. A milliliter (mL or ml) is a measure of volume, grams (g), kilograms (kg) and milligrams (mg) are measures of weight or mass.
1 teaspoon is 77 gr (grain). So 125 gr is about 2 teaspoons.
25*25*25 = 15625 cm^3 1 cm = 1 ml = 1 gram of water (since water density is about 1 gr/ml) therefore you will need 15,625 grams of water, or 15.625 kg
1000
100 gr because 1 kg = 1000 gr
Each 100 grams is 3.527 ounces .
Density of Coal may vary, depends on the type (structure) and form. Below are some density of coal : - Coal, Anthracite, solid 1.506 gr/ml - Coal, Anthracite, broken 1.105 gr/ml - Coal, Bituminous, solid 1.346 gr/ml - Coal, Bituminous, broken 0.833 gr/ml
We assume the volume is 300 ml (the question does not show that). 300 ml of 201 gr per ml = 300 x 201 = 60300 grammes = 60.30 kg. 300 ml of 5001 gr per ml = 300 x 5001 = 1500300 grammes = 1500.30 kg. Are you sure you did not mean densities of 20 and 500? The mass will then be 6kg and 150kg.
