Empirical formula is the simplest ratio of whole numbers of components in a compound
calculating for 100 g of compound 
                                                     N                                   O
mass                                          46.7 g                              53.3 g
number of moles                  46.7 g / 14 g/mol                 53.3 g / 16 g/mol 
                                                  = 3.33                               = 3.33
divide by the least number of moles 
                                                3.33/ 3.33 = 1.00              3.33/3.33 = 0
number of atoms 
N - 1
O - 1
therefore empirical formula is NO

mrs_skeptik [129]

Atomic number (Z) of tungsten is 74

Mass number (A) of tungsten is 184

Now:

Atomic number of an element = Number of protons = Number of electrons

Mass number = Number of Protons + Number of neutrons

In the case of tungsten

Total Number of electrons = 74

Jeffrey has already added 21 electrons

Number of electrons needed = 74 - 21 = 53

Ans (D) 53 more electrons are needed to complete the neutral atom of tungsten.

Calculate the mass of sucrose needed to prepare a 2000 grams of 2.5% sucrose solution.
meriva

Answer:

50 g Sucrose

Explanation:

Step 1: Given data

  • Mass of solution: 2000 g
  • Concentration of the solution: 2.5%

Step 2: Calculate the mass of sucrose needed to prepare the solution

The concentration of the solution is 2.5%, that is, there are 2.5 g of sucrose (solute) every 100 g of solution. The mass of sucrose needed to prepare 2000 g of solution is:

2000 g Solution × 2.5 g Sucrose/100 g Solution = 50 g Sucrose

Calculate the mass in grams for each of the following liquids.
WITCHER [35]
The density is calculated as mass per volume, so if we want to solve for mass, we would multiply density by volume.
For Part A: if we have a density of 0.69 g/mL, and a volume of 280 mL, multiplying these will give a mass of: (0.69 g/mL)(280 mL) = 193.2 g. Rounded to 2 significant figures, this is 190 g gasoline.
For Part B: if we have a density of 0.79 g/mL, and a volume of 190 mL, multiplying these will give a mass of: (0.79 g/mL)(190 mL) = 150.1 g. Rounded to 2 significant figures, this is equal to 150 g ethanol.
