What is the mass in grams of 6ml of water?
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.
How many joules are absorbed by the water with a mass of 8 kg in order to raise the temperature from 20 degrees to 70 degrees?
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 ============
Is 20 degrees Fahrenheit or 20 degrees celsius colder?
20 degrees Fahrenheit is colder.
WHAT IS 2O percent OF 250?
20% of 250 is 50
How many joules are needed to change the temperature of 100 g of water from 20 degrees Celsius to 40 degrees celsius?
8.200 J
How much sugar can be dissolved in 250 g of water at 20 degrees Celsius?
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.
What is the mass of potassium chlorate that will dissolve in 50 g of water at 20 degrees Celsius?
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.
How long to cook a 20 pound raw ham at 250 degrees?
A 20lb. raw ham cooked at 250 degrees should take 18 to 20 hours. Always be sure that the internal temperature reaches 190 degrees.
What form does water take at negative 20 degrees Celsius?
Water is a solid at -20 degrees Celsius
A pipet delievers 9.98g of water at 20 degrees celsius What volume does the pipet deliver?
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.
When 30 mL of water is added the graduated cylinder has a mass of 110 g. If a rock is added to the graduated cylinder the water level rises to 37 mL and the total mass is now 250 g. What is the densit?
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).
Weight of 20 liters of water?
The mass of 20 litres of water is 20 kilograms.
What is 35 degrees north- 20 degrees east?
water
What is the density of water at 20 degrees Celsius-?
The density of water at 20 degrees Celsius is approximately 0.998 g/cm³.
What body of water is 20 degrees north 90 degrees west?
The body of water located at 20 degrees north and 90 degrees west is the Gulf of Mexico.
Which sample of water contains the most heat energy 10 g at 10 degreescelsius or 20 g at 10 degrees celsius?
The sample of water that contains the most heat energy is the 20 g sample at 10 degrees Celsius because it has double the mass of the 10 g sample. Heat energy is directly proportional to mass, so the sample with more mass will contain more heat energy.
If 150 grams of sugar is dissolved in 100cm3 water what would be the mass of the solution?
Whether all of the sugar dissolved or not, and it would be very unlikely that it would all dissolve in that small an amount of water, the total mass of the solution or mixture would be 250 grams.
