  The   grams    are in  0.0150  moles  of  caffeine  C8H10N4O2

mass  =  moles  of C8H10N4O2  x  molar mass  of  C8H10N4O2

= 194g/mol x  0.0150mol =  2.91  grams

there  is  2.94  grams  in  0.01150  of  caffeine

Which substance is an electrolyte? A) O2 B) Xe C) C3H8 D) KNO3
mixer [17]
Answer:
            KNO₃ is an electrolyte.

Explanation:
                   Electrolyte is any specie which when dissolved in water produces a cation and anoin. Electrolytes has the ability to conduct electricity. In given options O₂, Xe and C₃H₈ are non electrolytes because they cannot dissociate into cation and an anion due to their covalent bonds or monoatomic nature. The dissociation of Potassium Nitrate is as follow,

                                       KNO₃    →   K⁺ ₍aq₎  +  NO₃⁻ ₍aq₎

in a typical person, the level of glucose is about 85 mg/ 100 mL of blood. if an average body contains about 11 pt of blood, how
Vanyuwa [196]

Let's note that 1 pint = 473.1765 mL, so 11 pints should be 5204.9415 mL.

We make a proportion out of the word problem

(85 mg glucose/ 100 mL) times (1 g/ 1000 mg) = 4.4242 grams of glucose

Find the empirical formula of the following compounds:
Aneli [31]

The empirical formula of the following compounds 0.903 g of phosphorus combined with 6.99 g of bromine.

<h3>What is empirical formula?</h3>

The simplest whole number ratio of atoms in a compound is the empirical formula of a chemical compound in chemistry. Sulfur monoxide's empirical formula, SO, and disulfur dioxide's empirical formula, S2O2, are two straightforward examples of this idea. As a result, both the sulfur and oxygen compounds sulfur monoxide and disulfur dioxide have the same empirical formula.

<h3>How to find the empirical formula?</h3>

Convert the given masses of phosphorus and bromine into moles by multiplying the reciprocal of their molar masses. The molar masses of phosphorus and bromine are 30.97 and 79.90 g/mol, respectively.

Moles phosphorus = 0.903 g phosphorus \frac{mol phosphorus}{ 30.97 g phosphorus}= 0.0293 mol

Moles bromine 6.99 g bromine\frac{mol bromine}{79.90 g bromine}=0.0875 mol

The preliminary formula for compound is P0.0293Bro.0875. Divide all the subscripts by the subscript with the smallest value which is 0.0293. The empirical formula is P1.00Br2.99 ≈ P₁Br3 or PBr3
