What is the mass in grams of 2.50 mol of sulfur?
To find the mass of 2.50 mol of sulfur, you need to multiply the number of moles by the molar mass of sulfur. The molar mass of sulfur is approximately 32.06 g/mol. Therefore, the mass of 2.50 mol of sulfur is 2.50 mol x 32.06 g/mol = 80.15 grams.
What is a period of earths history that lasted 245 to 208 million years ago?
The period of Earth's history that lasted 245 to 208 million years ago is the Triassic period. This period followed the Permian period and preceded the Jurassic period. It was a time of recovery and diversification of life after the mass extinction at the end of the Permian period.
How many moles are contained in 245g of potassium bromide?
To find the number of moles in 245g of potassium bromide, first calculate the molar mass of KBr by adding the atomic masses of potassium (39.10 g/mol) and bromine (79.90 g/mol). The molar mass of KBr is 119.00 g/mol. Then, divide the given mass by the molar mass: 245g / 119.00 g/mol = 2.06 moles of potassium bromide.
Which is colder a gas at -143 degrees or a gas at -245 degrees?
A gas at -245 degrees is colder than a gas at -143 degrees. Temperature is directly related to the average kinetic energy of particles in a substance, and the lower the temperature, the slower the particles are moving, making it colder.
Wegener thought that all of the present continents were once joined 245 million years ago in a landmass he called?
The last super-continent is called Pangaea, which was formed about 245 million years ago. Some believe that Pangaea wasn't the first time all the continents were combined. There is evidence that there was another super-continent way before 245 million years ago that is called Rodinia (which separated for a while, then formed back together to form Pangaea, the latest super-continent).
What is the density of a rock which has a mass of 35 grams and a volume of 7.0 cubic centimeters?
To calculate density, you must calculate the mass divided by the volume. Therefore, density=234 g/ 2.9 cm3 = 80.6896... g/cm3 or 81 g/cm3 using significant figures.
If a graduated cylinder has a mass of 200g when 26ml of a liquid is added and it rises to 245 g What is the density of the liquid?
The increase in mass is 45g (245g - 200g) due to the added liquid. This corresponds to a volume of 26ml because 1g/ml is the density of water (and marketed) liquids. Therefore, the density of the liquid is 45g / 26ml = 1.73 g/ml.
A small airplane takes on 245L of fuel If the density of the fuel is 0.821 g mL what mass of fuel has the airplane taken on?
To find the mass of the fuel taken on by the airplane, you need to multiply the volume of fuel by its density. First, convert the density to g/L by multiplying 0.821 g/mL by 1000 to get 821 g/L. Then, multiply 245 L (volume) by 821 g/L (density) to find the mass of the fuel taken on, which is approximately 200,845 grams of fuel.
How many ounces is 245 grams?
225 grams = 7.94 ounces.
Change 245 milligrams to grams?
245 milligrams = 0.245 gram
What is the percent by mass of 35g of sodium chloride mixed with 245ml of water?
Calculate the mass of water (density: 1 g/ml) --> 245 ml * 1 g/ml = 245 g of water wt % = 35 g / (35g + 245g) * 100% = 12.5%
