How many molecules are there in 450 grams of NaSO4?
Weight of NaCl used (250g)/Total molecular weight x Avagadro's number = total molecules of NaCl.
How many grams in 2 moles of HCI?
A Mole is the molecular weight expressed in grams. So for example water H2O: the molecular weight of oxygen is 16 and hydrogen is 1 so the total molecular weight of water is 18 (16 for one atom of oxygen plus 2x1 for the two atoms of hydrogen). For HCl, the atomic weight of Cl is 35 and H is 1 so the total molecular weight is 36. So 1 Mole of HCl is 36 grams. If you have 2 moles, it would be 72 grams.
Do water vapor molecules weight less than other gases?
Water vapor molecules are heavier than some gasses and lighter than others. The weight is based on their molecular weight which is the total of the atomic weights of the atoms in the molecule. The atomic weight of an atom is the total number of protons and neutrons in the atom. Some examples: Oxygen gas (O2) has has a molecular weight of 32 (two oxygen atoms each weighing 16) . Hydrogen gas (H2) is 2 (two hydrogen atoms each weighing 1). Water vapor (H2O) molecules have a molecular weight of about 18. Helium (He) has molecular weight of 18. Carbon Dioxide gas (CO2) is 44.
How many total molecules are there in 3be2br?
The total number of atoms of the reactants should be equal to the total number of atoms of the products. The total number of molecules of the reactants should be equal to the total numbers of molecules of the products

How many inches in a 100 grams of yarn?
Your answer depends on the weight of the yarn -- thread weight yarn weighing a total of 100 grams will contain more yardage than a bulky weight yarn ball weighing 100 grams.
How many molecules are there in 450 grams of NaSO4?
Weight of NaCl used (250g)/Total molecular weight x Avagadro's number = total molecules of NaCl.
How many grams are in a tablespoon of mayonnaise?
A tablespoon of butter contains 11.52 grams of fat, which is somewhat less than the usual 14 grams of fat for a tablespoon of oil. Here's a comparison: Butter, 1 T Total saturated 7.29 Total monounsaturated 2.98 Total polyunsaturated 0.43 Olive Oil, 1 T Total saturated 1.86g Total monounsaturated 9.85g Total polyunsaturated 1.42g There's about 33 mg of cholesterol in a tablespoon of butter. Here's the USDA's nutrient values site on 1 Tablespoon of butter: Go to the USDA National Nutrient Database for Standard Reference http://www.nal.usda.gov/fnic/foodcomp/search/ and type in butter, click Submit, then choose Butter, Salted, click Submit, then choose 1 Tablespoon, click Submit a third time, and you'll get to the nutrient values for 1 tablespoon of butter.
What is the average size and weight of a cat's heart?
In a very old study performed on a small number of cats (among other animals), Don R. Joseph, MD found the average weight of an adult cat heart to be approximately .457 percent of total body weight. In 11 male cats sampled, the average heart weight was 13.80 grams (with an average total body weight of 3078 grams). In 15 female cats sampled, the average heart weight was 12.34 grams (with an average total body weight of 2650 grams). See below for the Source.
What is the reactant of 10.0 grams of total mass What is the chemical reaction?
It is possible to have ten grams of anything. Specifying the total weight tells you nothing about which reactant you have or what reaction it will undergo.
A bottle and honey weight is 1500 grams if you take the weight of half honey and bottle its weight 900 grams what is the remaining weight of honey?
Total weight = weight of honey + weight of bottle or equivalently: Total weight = 1/2 weight of honey + weight of bottle + 1/2 weight of honey then plugging in for the values we know: 1500g = 900g + 1/2 weight of honey so 1/2 weight of honey = 1500g - 900g = 600g
Average weight of human brain?
The adult human brain is about 2% of the total body weight
