C6H12: The Atomic Mass of carbon is about 12 and that of hydrogen about 1. Therefore, the atomic mass of carbon plus 2 hydrogens is about 14, and 84/14 = 6

How do you calculate the mass of acetic acid and baking soda?
To calculate the mass of a substance, you need to know its molar mass and the amount of the substance in moles. The molar mass of acetic acid is approximately 60g/mol and for baking soda (sodium bicarbonate) is about 84g/mol. Once you have the number of moles of the substance, you can use the formula mass = number of moles x molar mass to calculate the mass.
How many pounds is 84g?
It is equal to 0.1851 pounds approximately. Kilogram is the metric unit and pound is the imperial unit for mass. 1 Kilogram is 2.204 pounds. So we multiply kg by 2.204 to get the equivalent pounds.
What is the density of object with 84 grams and 21 cubic centimeters?
Density = Mass/Volume = 84g / 21 cc = 4 grams per cubic centimetre.
If 5 grams of NaHCO3 decomposes what is the mass of the carbon dioxide used?
I just had this question on my chem homework so I'll see if I can help. First thing you need to do is balance the equation. The balanced equation should look like this: 2NaHCO3 -----> Na2CO3 + H2O +CO2 With that out of the way we can start converting. The Molar Mass of NaHCO3 is 84 (or close to it, depending on how you round your decimals) So we do 5g NaHCO3/ 84g NaHCO3. That should give you about 0.059. Next we do 0.059/2mol NaHCO3, because we know from the balanced equation that we have a 2:1:1:1 ratio. That should give you about 0.0295. Now we find the Molar Mass of CO2, which is around 44. Lastly, we go 0.0295x44 and that should give us the answer. I got 1.3g of CO2 as my answer. I hope I was able to be of some use. :)
When 84G of magnesium carbonate was heated 40G of magnesium oxide was collected why did the mas go down?
The decrease in mass is likely due to the release of carbon dioxide gas during the process of heating magnesium carbonate to form magnesium oxide. The gas escapes, leading to a decrease in the overall mass of the sample.
A rock has a mass of 84 grams and a volume of 12 cc what is density?
Density is calculated by dividing the mass of an object by its volume. In this case, the rock has a mass of 84 grams and a volume of 12 cc. To find the density, you would divide the mass (84g) by the volume (12cc), resulting in a density of 7 grams per cubic centimeter (g/cc).
How many calories in portabello mushrooms?
One 3 oz or 84g uncooked portabella mushroom contains approximately 22 calories. For the calories in other vegetables, see the page link, further down this page, listed under Related Questions.
What is the maximum number of grams of NH4Cl that will dissolve in 200 grams of water at 70?
The solubility of NH4Cl in water at 70°C is approximately 84 grams per 100 grams of water. To find out the maximum amount that will dissolve in 200g of water, you can use a proportion: (84g / 100g) = (x / 200g). Solving for x gives you approximately 168 grams of NH4Cl that will dissolve in 200g of water at 70°C.
How do you prepare 500cm3 of NaHCO3 solution of 1M concentration?
Weighting half value of 23+1+12+(3x16) = 84/2 = 42 gram NaHCO3 gives you 0.5 mole of it, to be dissolved in about 200 mL and there after to be filled up to 500 mL (= 500 cm3) will result in a 0.5 mol / 500 mL = 0.5 mol / 0.5 L = 1 mol/L = 1M NaHCO3
198g how many kg?
Unit conversion can be hard, and converting grams into kilograms can be tricky. 198 grams is the equivalent of .198 kilograms.
What does it mean that Wash organic layer with 1.0 ml of 1M aqueous sodium bicarbonate?
1m is the molarty of the solution meaning the concentration is 1 mol of baking soda (sodium bicarbonate) to every liter of water. 1 mol of sodium bicarbonate is 84g. so for 1ml of water with a molarity of 1 divide 84g by 1000 which is 84mg and add that to 1ml of water. as far as wahing the organic layer i think it means washing any water from the solution but i may be wrong idk.
How many carbs in one cup of wheat flour?
Gold Medal brand Whole Wheat Flour Nutrition Facts label says 1/4 cup (30g) has 21g Total Carbohydrate, 3g Dietary Fiber, and 18g Other Carbohydrate. So a cup would have 84g of Carbohydrate, 12g Dietary Fiber, and 72g Other Carbohydrate.
