The effect of vapor condensation in the neck a beryl type pipet have on the reported molar mass?
it would give a higher molar mass b/c we are actually measuring the condensed liquid so the measured pipet would give higher mass. the higher the pipet is the higher molar mass.
Ethanol c2h5oh and methyl ether ch3och3 have the same molar mass.W hich has a higher boiling point?
ethanol has a higher boiling point- of 78°C :)
Why is CS2 a liquid at room temperature whereas CO2 is a gas at room temperature?
CS2 has a higher molar mass than CO2
How many grams of HCl can be prepared from 2.00 mol H2So4 and 150 g NaCl?
2NaCl + H2SO4 ----> 2HCl + Na2SO4 *molar mass of H2SO4 is 98.09g *molar mass of NaCl is 58.44g *molar mass HCl is is 36.46g Moles NaCl = 150 g / 58.44 = 2.56 The ratio between NaCl and H2SO4 is 2 : 1 so NaCl is the limiting reactant We would get 2.56 mol HCl => 2.56 mol x 36.46 g/mol = 93.3 g
If you know the molar masses of the reactants in a chemical reaction can you determine the molar masses of the products?
If you know know the molar masses of the reactants in a chemical reaction you can determine the molar masses of the products because the combined molar masses of the reactants equals the combined molar masses of the products.
Which ions is the limiting reagent and which is the reagent in excess when barium sulphate is made?
When barium sulfate is made, the limiting reagent is the one that is completely consumed in the reaction and determines the amount of product formed. In this case, if barium ions (Ba2+) and sulfate ions (SO42−) are the reactants, the limiting reagent would be the one that is present in lower molar quantity. The one in excess would be the one that is present in higher molar quantity. Without the quantities of each ion provided, it is difficult to determine which is the limiting reagent and which is in excess.

Why ethanol with molar mass of 46gmol boils at 78 degree Celsius than water with molar mass og 18gmol boils at 100 degree Celsius?
Hydrogen bonds in water are much stronger than in ethanol. For the same reason the density of the liquid is also higher.
what are the gases diffuse at lowest rate?
gases with the higher molar mass
Having a misclibrated thermometer of 3 higher than actual what will be its molar mass?
sorry, but that makes no sense unless put into some context that I don't know. First, 3 of what unit higher, second thermometer is temperature, which does not relate to molar mass. Molar mass stays constant on an element or compound.
Which has greater mass mole of silver or mole of gold?
gold, as it has a higher molar mass
Cyclopropane or propylene has higher standard molar entropy?
Propylene due to the molecular structure.
Which is the limiting reactant when masses of reactants are same?
You must first convert the mass of each reactant into moles of each reactant. Having the same mass does not mean that the amount of each reactant is the same, because each reactant has its own unique molar mass. Refer to the related link below for instructions on determining limiting reactants, also called limiting reagents.
Which has a greater mass.. one mole of silver or one mole of gold?
Gold, as it has the higher molar mass.
How do you calculate the percent yield of an element in a reaction?
The actual yield is given within the worded problem. The theoretical yield however is to be found. In order to calculate the theoretical yield, you need to convert the mass of the limiting reagent (LR) to the mass of the reagent in excess (ER). To find the limiting reagent, you need to first convert the mass of the limiting reagent to the mass of the reagent in excess (to find the theoretical yield)A. Convert mass of limiting reagent to mass reagent in excess (mass --> mass); in other words, find the mass of the reagent consumed.1. Multiply the mass of the limiting reagent by the # molecules of the reagent in excess and its molar mass.2. Divide the above by the # of molecules LR which is multiplied by its molar mass.Mass LR x # molecules ER x molar mass ER-- # molecules LR x molar mass LR3. Subtract the original mass of reagent in excess and the consumed reagent in excess.Original mass Reagent in Excess - Consumed Reagent in Excess= Reagent leftover/unused (theoretical yield).B. Find the percent yield of the product.--- Actual YieldTheoretical Yield x 100%

Does aluminum have a higher specific heat capacity then lead?
no because the molar mass of lead is great than aluminum
