density = mass/volume = 250g/45cm3 = 5.6g/cm3 (rounded to 2 sig figs)
Density is equal to mass divided by volume (d= m/v). So m= 250 g and v = 125 cm cubed (cm3), there fore density is 2 g/cm3.
assuming a density of 1g/ml, then 250g
Compared to 250 g of gaseous nitrogen 250g of liquid nitrogen has greater density, viscosity, surface tension, and commercial value.
15% of 250g = 37.5g
250g 250g are in one cup
It is: 2000g+250g = 2250 grammes
Grams is a unit of weight measurement. Cups measure volume. While you can weigh different things and have them all weigh 250g, these items will not equal the same amount of cups. For example, 250g of salt would take up less "space" than 250g of popped popcorn. So, since all foods weighing 250g may fill a different amount of cups, your question can only be answered if you are asking about a specific food.
This question cannot be answered sensibly. A litre is a measure of volume, with dimensions [L3]. A kilogram 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 litre of air and a litre of water. They will have very different masses.
250g of cream cheese would be the best.
3.5kg = 3500g 3500g / 250g = 14 Therefore, 3.5kg will make 14 bags of 250g sweets
