Approximately 6g. The density of pure water at 20 degrees centigrade and standard atmospheric pressure is 1 g/ml. The answer is approximate since the water may not be chemically pure and you do not give a temperature or pressure.
q(joules) = mass * specific heat * change in temperature ( 8 kg = 8000 grams ) q = (8000 grams H2O)(4.180 J/gC)(70o C - 20o C) = 1.7 X 106 joules ============
20 degrees Fahrenheit is colder.
20% of 250 is 50
8.200 J
Approximately 204 grams of sugar can be dissolved in 250 g of water at 20 degrees Celsius. This is the saturation point for sugar dissolving in water at this temperature.
The solubility of potassium chlorate in water at 20 degrees Celsius is approximately 5.7 g/100 g of water. Therefore, the mass of potassium chlorate that will dissolve in 50 g of water is 2.85 g.
A 20lb. raw ham cooked at 250 degrees should take 18 to 20 hours. Always be sure that the internal temperature reaches 190 degrees.
Water is a solid at -20 degrees Celsius
Water melts at 0 degrees Celsius, not 20 degrees. Water has a hexagonal close-packed structure when it is in solid form.
At -20 degrees Celsius, water is in the solid phase and is frozen.
To calculate the volume of water delivered by the pipette, you need to convert the mass of water to moles using its molar mass (18 g/mol). Then, you can use the density of water (1 g/mL) at 20 degrees Celsius to convert moles to volume. The volume delivered by the pipette would be approximately 9.98 mL.
The mass of 20 litres of water is 20 kilograms.

The mass of water added is 110 g minus the initial empty cylinder mass. The mass of the rock is the total mass of 250 g minus the mass of the water and empty graduated cylinder. The density of the rock can then be calculated using the mass of the rock and its volume (37 mL - 30 mL).
The body of water located at 20 degrees north and 90 degrees west is the Gulf of Mexico.
The density of water at 20 degrees Celsius is approximately 0.998 g/cm³.
