Why do you use algebra in science?
Because equations are part of Science to explain the diversity of it. Example: H2o and other formulas....
What is the value of x When a 1.63 g sample of MgCl2xH2O is heated to remove all water a mass of 0.762 g remains?
You begin with 1.63 g of MgCl2•xH2O. You end up with 0.762 g MgCl2. That means you lost 1.63 - 0.762 = 0.87 g of H2O. 0.762 g MgCl2 / 95.21 g (molar mass) = .00800 mol MgCl2 0.87 g H2O / 18.02 g (molar mass) = .048 mol H2O x = mol solute / mol solvent x = .048 mol H2O / .00800 mol MgCl2 x = 6 MgCl2•6H2O
What is the equation for reacting KHCO3 with H2O?
Khco3+h2o
How do you balance Cl2O7 plus H2O equals HClO4?
cl2o7+h2o
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 ============
How many moles are there in 1500 grams of water?
0.998 g/cm³ is the density of water so you go 150g/ (0.998g/cm^3) and that gives your volume or ammout and that is 150.3006ml or 150.3006cm^3 * * * * * True at around 20 deg C, or room temperature. At its maximum (at a pressure of 1 atmosphere), the density of water is 0.9999720 grams per cm3 at 4 deg C. Than means 150 grams has a volume of 150.0042001 cm3. At its least dense it is 0.9584 grams/cm3 and the volume of 150 grams would be 156.511 cm3 approx.
What is the density of water in grams per ounces?
Water has a molecular formula of H2O. The molar mass of H2O is 18.0153 g/mol and has a density of 1 g/cm3. 1 fluid ounce is 29.57 milliliters, or 29.57 cm3. This means that there are 29.57 grams per fluid ounce of water.
What is the gram formula mass for H2O?
The gram formula mass for H2O is 18.015 g/mol.
What is the mass in grams of 4.5 moles of h2o?
0.25 mole of H2O
What is the mass of 2.1 moles H2O?
The molar mass of water (H2O) is approximately 18.015 g/mol. Therefore, the mass of 2.1 moles of H2O would be approximately 37.83 grams.
Find the mass in grams of 1.54 moles of H2O?
To find the mass of 1.54 moles of H2O, you can use the molar mass of water. The molar mass of H2O is 18.015 grams/mol. Therefore, the mass of 1.54 moles of H2O would be 1.54 moles * 18.015 grams/mol = approximately 27.75 grams.
What is the mass of 1 cm3 of a mateial?
The mass of a given volume of a material is dependent on the material's density, and thus its molecular weight. So, this will differ for every type of material, and there is therefore no absolute weight for 1ml (cm3) of a material. The only universal measure of mass that holds for all materials is the 'mole.' A mole is defined as 6.022 x 1023 atoms of a given substance. Multiplying the atomic mass of a given element or molecular weight of a given compound by this number yields the mass of one mole of the element, in grams. If the density of a given substance is known, the mass per cm3 can then be calculated. Frequently in chemistry, the density of a substance is compared to the density of water (H2O), which is 1g/ml.
What is the mass of water molecule?
1 mole H2O = 18.015g H2O = 6.022 x 1023 molecules H2O 1.5 x 1023 molecules H2O x 18.015g H2O/6.022 x 1023 molecules H2O = 4.5g H2O
How many moles are in 8g of H2O?
To calculate the number of moles in 8g of H2O, we must first calculate the molar mass of H2O (18.015 g/mol). Then, we can use the formula moles = mass / molar mass to find that there are approximately 0.444 moles of H2O in 8g.
What is equivalent weight of Sodium Hypochlorite. Also explain why?
The equivalent weight of Sodium Hypochlorite (NaClO) is 74.44 g/mol. This is because one mole of NaClO contains one mole of available chlorine, which has an atomic weight of 35.45 g/mol and one mole of sodium with an atomic weight of 22.99 g/mol. Therefore, the equivalent weight is the sum of the atomic weights of chlorine and sodium in NaClO.
How many moles of H2O are there in 1.0 g of H2O?
There are 0.0556 moles of H2O in 1.0 g of H2O. This calculation is obtained by dividing the given mass (1.0 g) by the molar mass of water (18.015 g/mol).
What is the mass of 2 mole of h2o?
36g
