What happens when a baby molar cracks in half?
My daughter's baby molar shattered in the back. It caused an infection down to the root. It was extracted to allow the adult molar to come in after it. A spacer had to be put in to hold the position for the new molar which could take a few years to grow in. Prior to the extraction she had to go on antibiotics to clear up the infection, otherwise, the anesthesia wouldn't work.
Difference between parachor and rheochor?
parachor is depend on the surface tention of the liquid and its molar volume rheocor is depend upoun the viscosity of a liquid . both are additive and constiitutive property.

A factor is a number or quantity that when multipled with another produces a given number or expression.
The city in India that exports the largest quantity of oranges?

How many moles of strontium hydroxide are in 4.25 g of strontium hydroxide?
You must first find the molar mass of the element or compound. Use the periodic table (see the link to the left of the answer). If the chemical is an element, just read off the atomic mass from the periodic table. If it is a compound, you must know the molecular formula, and then you find the total molar mass of the compound by adding up the atomic masses of each atom in the compound. The unit of the molar mass will be in grams per moles (g/mole)Once you have the molar mass, you can easily convert from grams to moles, and also from moles to grams.Number of moles = (# of grams) ÷ (molar mass)Number of grams = (# of moles) × (molar mass)Here are a two examples:Example 1:How many moles are in 5 grams of O2?The molar mass of O2 = 16.00 g/mole x 2 (for 2 atoms of oxygen) or 32.00 g/mole.5 g of O2 ÷ (32 g/mole) = 0.15625 molesExample 2:How many grams does 4 moles of NH3 weigh?The molar mass of NH3 = 14.01 + (3 × 1.01) = 17.04 g/mole4 moles × 17.04 g/mole = 68.16 gramsGrams in a MoleIn chemistry, a mole is considered to be Avogadro's number (6.02 × 1023) of molecules (or anything) of a substance - so depending on the density of the substance, the mass of that amount of the substance could vary widely. One mole of hydrogen, for example, would have a different mass than one mole of lead. The question compares two different measurements of a given substance, rather like asking "how heavy is a gallon?". The question becomes "A gallon of what"?
A one molar solution of NaOH in water contains?
One liter of a one molar solution of NaOH in water contains 40g of NaOH. The quantity must be known.
Why you prefer molar specific heat as compared to the simple specific heat?
In chemistry instead mass in kg it would be nice to deal the quantity in moles. Hence molar specific heat is best fit.
If the quantity of 1 mole of carbon is 12 what can be said about the quantity of 1 mole of lithium?
it can be said that 1 mole oflithium is equal in mass to its molar mass wwhich is 6.94 g/mol
What is the difference between partial molal quantities and partial molar quantities?
During the determination of the partial molal quantities the weight of the solution to which a substance is added is taken into consideration while in case of the partial molar quantity the volume is taken into consideration.
The molar heat of fusion for water is 6.008 kJmol What quantity of heat energy is released when 253 g of liquid water freezes?
When the molar enthalpy of fusion for water is 6.008 kJ/mol, there is 84.4 kJ released when 253 grams of liquid water freezes. 84.4 kJ
What is molar conductivity at infinite dilution?
Molar conductivity at infinite dilution is when molar conductivity is limited. Molar conductivity is when electrolyte conductivity is divided by molar concentration.
If you are giving a quantity of solute in grams and need to convert it to moles divide the grams by?
The molecular weight. So you'll have to calculate that for the solute first. The molar mass of the solute, which is measured in grams/mole.
Is the molar mass a fixed quantity for a particular substance?
For most purposes, the molar mass of any particular substance remains the same. However to be precise I will note that there are isotopic variations which can affect molar mass. In other words, it is normally expected that a given substance will have a certain mixture of isotopes giving a certain mass, but a substance obtained from one source might have a different isotope ratio than the same substance obtained from a different source.
What is the molar mass of SiC?
Molar Mass of Carbon + Molar Mass of Silicon = Molar Mass of SiC. 12.0107 + 28.0855 = 40.0962 g / mol.
How would you prepare a 1 mole solution of lactose?
Find out the molecular weight of LactoseAdd that many grams of Lactose into a 1000ml volumetric flaskMake up the volume to 1000ml with waterYour 1 Molar solution of Lactose is ready---------------The molar mass of lactose is 342,3 g/mol; the solubility of lactose is 216 g/L at20 0C. Consequently you cannot prepare a molar solution of lactose.
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.
What is the molar concentration of nitric acid?
16 molar.
