Compared to 250 g of gaseous nitrogen 250g of liquid nitrogen has greater what?
250g of liquid nitrogen has greater density than 250g of gaseous nitrogen. This is because the liquid form of nitrogen is more tightly packed, with particles in closer proximity, compared to the gaseous form where particles are more spread out.
How many moles of molecules are there in 250g of hydrogen nitrate?
To find the number of moles in 250g of hydrogen nitrate (HNO3), we first need to determine the molar mass of HNO3. The molar mass of HNO3 is 63.01 g/mol. Then, we can calculate the number of moles by dividing the given mass by the molar mass: 250g / 63.01 g/mol = approximately 3.97 moles of HNO3 molecules.
A solution contains 30 g of calcium chloride in 250 g of water express the mass percent?
The solution has a total mass of 30 + 250 = 380 g. The mass percent of calcium chloride in this solution is 100(30/380) = 7.9 %, to the justified number of significant digits.
What is nitrogen at 20 degrees?
Nitrogen is a colorless, odorless, and tasteless gas at room temperature of 20 degrees Celsius. It is the most abundant element in Earth's atmosphere, making up about 78% of the air we breathe. Nitrogen is essential for life and is commonly used in fertilizer production and various industrial applications.
What is the number of moles in 4.50 grams of H2O?
There are four molecules of water in 4H2O. One molecule of water is written as H2O. The subscript 2 tells you that there are two H(hydrogen) atoms. Since there is no subscript after the O there is one O(oxygen) atom. Now back to 4H2O. The coefficient 4 tells you there are four molecules of H2O. Therefore there are eight H(hydrogen) atoms and four O(oxygen) atoms.

What is the best estimate of the mass of the anaconda?
250 kilograms
How heavy is 250 litres of water?
For standard water under standard conditions ... 1 liter of water has 1 kilogram of mass ===> 250 liters has 250 kg of mass. On the surface of the earth, 1 kg weighs 2.20462 pounds ===> 250 kg weighs (250 x 2.20462) = 551.155 pounds
What is the density of 25 mass and 250 cm?
Density is mass divided by volume. To calculate density we need both mass and volume, so we can't determine the density with just the given information of 25 mass and 250 cm.
