We calculate the theoretical yield by taking the given mass of the reactants and multiplying it by the molar mass of the reactants and the molar mass of the products. The unites will cancel out and leave grams in the end. What does the percent yield tell you? The percent yield is the...

Give an example of calculating percentage yield in chemistry. Can you determine the molecular formula from its percent composition? How do you find the percent composition of a hydrate? How to convert grams to ounces with a formula How do you calculate percent composition from gas chromatography?
Given 2 grams of Cu(NO3)2 and excess NaOH, calculate how much Cu(OH)2 can be produced? The molar mass of NaOH is 40g/mol, how many grams of NaOH are required to yield 0.65 mol? How many moles of H2O are produced when 2....
Answer 2:The salt water has a density of 1.1 grams/mL. Finding Volume by Displacement If given a regular solid object, you can measure its dimensions and calculate its volume. Unfortunately, few objects in the real world can have their volume measured this easily! The rest of the time, yo...
Sometimes you're given a value inmolesand need to convert it to grams. To do this, first calculate the molar mass of a sample. Then, multiply it by the number of moles to get an answer in grams: grams of sample = (molar mass) x (moles) ...
Most of them pause, shrug their shoulders, and then reply, “I’m not sure, maybe…” then take a guess at how much weight they want to lose. The amount of weight you want to lose (or gain) doesn’t have to be a guessing game. There’s a formula to calculate your goal weight ...
Metric: 100 grams US: 1 cup While you can eyeball the size of fruits/vegetables to get a decent estimate – small, medium or large, for a more accurate number, you should use a food scale. You might be surprised what qualifies as “small” or “large” when eyeballing. ...
I have no idea how to calculate the reduced time that would be applicable in this case and your help would be greatly appreciated. Thanks in advance! Reply Sue on 2/4/14 at 8:38 am I’ve had this same rice cooker for “YEARS”! I love it and I’m lost without it. Sure, ...
