Answer:

Area of rectangular poster = \frac{3}{16} yard²

Explanation:

P.S - The exact question is -

Given - A rectangular poster is \frac{1}{4} yard wide and \frac{3}{4} yard tall.

To find - What is its area ?

Proof -

We know that ,

The area of rectangle = Length × Breadth

Here,

Given that,

Length of rectangle = \frac{3}{4} yard

Breadth of rectangle = \frac{1}{4} yard

∴ we get

Area of rectangular poster = \frac{3}{4} × \frac{1}{4}  yard²

                                          = \frac{3}{16} yard²

⇒Area of rectangular poster = \frac{3}{16} yard²

What is the approximate percent by mass of potassium in KHCO3?
lozanna [386]

Answer:

The mass percent of potassium is 39%

Option C is correct

Explanation:

Step 1: Data given

Atomic mass of K = 39.10 g/mol

Atomic mass of H = 1.01 g/mol

Atomic mass of C = 12.01 g/mol

Atomic mass of O = 16.0 g/mol

Step 2: Calculate molar mass of KHCO3

Molar mass KHCO3 = 39.10 + 12.01 + 1.01 + 3*16.0

Molar mass KHCO3 = 100.12 g/mol

Step 3: Calculate mass percent of potassium (K)

%K = (atomic mass of K / molar mass of KHCO3) * 100%

%K = (39.10 / 100.12) * 100%

%K = 39.05 %

The mass percent of potassium is 39%

Option C is correct
