The answer & explanation for this question is given in the attachment below.
We are asked to solve for the arc length of the intercepted arc and the formula is shown below:
Arc length = 2*pi*r(central angle/360°)
r = 5 feet
central angle = 10°
Solving for the arc length, we have:
Arc length = 2*3.14*5 (10/360)
Arc length = 0.872 feet
The arc length is 0.872 feet.
Answer:
Number of moles = 1.97 mol
Explanation:
Given data;
Number of moles of I₂ = ?
Mass = 500.0 g
Solution:
Number of moles = mass/ molar mass
Molar mass of I₂ = 253.8 g/mol
Number of moles = 500 g / 253.8 g/mol
Number of moles = 1.97 mol
