Answer: it would be 0.026 moles
Explanation: PV=nRT, P is the pressure of gas, V is the volume it occupies n is the number of moles of gas present in the sample, R is the universal gas constant which is equal to 0.0821 atm L/mol K and T is the absolute temperature of the gas
Answer:
The chain of colored boxes represent the first eight amino acids in the beta chain of hemoglobin. The sixth position in the normal beta chain has glutamic acid, while sickle beta chain has valine. This is the sole difference between the two
Explanation:
In order to convert the moles of a substance to grams, you will need to multiply the mole value of the substance by its molar mass. More commonly written for this application as: where, is the molar mass of the substance.

Answer:
9.31 g = 0.00931 kg
Explanation:
We need to tell that 9.31 gram is same as what. There are many units that measure the meass of an object like milligram, kilogram, centigram etc.
The relation between kilogram and gram is as follows :
1 kg = 1000 g
or
1 g = 0.001 kg
If we change 9.31 gram to kg, we get :
9.31 g = (9.31 × 0.001) kg
or

Hence, 9.31 g is the same mass as 0.00931 kg.
Answer:
The total mass of reactants equals the total mass of products
Step-by-step explanation:
The <em>Law of Conservation of Mass</em> states that matter cannot be created or destroyed in a chemical reaction:
Reactants ⟶ products
Thus, if you start with a given mass of reactants, the total mass of products will equal the total mass of reactants.
