Dimensional analysis is based on the principle that physical quantities that are equated must be represented in measures of the same basic quantities (e.g mass, length, or time) in order to draw conclusions about their relationships.

If Gold cost $8.00 per ounce

Then $15.00 will cost:

\mathbf{x = \dfrac{\$15.00 \times 1  \ ounce}{ \$ 8.00}}

x = 1.875 ounces

Assuming x to be the amount of ounce, then Gold of $15.00 will cost 1.875 ounces.

Now, given that:

1000g = 1kg

1 kg = 2.2 lbs

1 lb = 16 oz

Then, to determine the amount of gram that is equivalent to 1.875 ounces, we have:

Since 1 lb = 16 oz

2.2 lbs = (2.2*16) oz

= 35.2 oz

Since 1 kg = 2.2lbs = 35.02 oz

∴

x(g) =  1 kg

1000 g = 35.02 oz

1 (g) = 35.02/1000 oz

1 (g) = 0.03502 oz

Thus, If 1 (g) = 0.03502 oz

x(g) = 1.875 oz

\mathbf{x(g) = \dfrac{1.875 \ oz \times 1 \ g}{0.03502 \ oz}}

x  = 53.54 g

Thus, we can conclude that amount of the grams you can purchase for $15.00 is 53.54 grams

State the guideline you can use to predict the formula of:
Cerrena [4.2K]

We can predict formula of ionic compounds by:

  • Take a look at where the elements are listed on the periodic table.
  • The amount of electrons that an element would need to gain or lose in order to resemble an atom of a nearby noble gas is one of the similarities that atoms in the same column as one another (group) tend to display.
  • Alkali metal group I ions have +1 charges.
  • Alkaline earth metals (group 2 ions) have a +2 charge.
  • Nonmetal group 6 ions have a charge of -2.
  • Halides in group 7 have a -1 charge.
  • The charges of the transition metals cannot be predicted in a straightforward manner.
  • Check out a table of charges (valences) to see potential values. The +1, +2, and +3 charges are most frequently employed in beginning and general chemistry courses.
  • Keep in mind that the positive ion is always stated first when writing an ionic compound's formula.

These are the few guidelines we can use to product formula.
