1. The speed limit on most city streets is (25 miles). How many meters per minute

irina1246 [14]

Answer:

$Speed = 670.56 \frac{m}{min}$

Explanation:

Given

$Speed = \frac{25 mi}{hr}$

Required

Convert to meters per minutes

$Speed = \frac{25 mi}{hr}$

Start by converting the speed from miles to meters

$1\ mile = 1609.34\ meters.$

So, we have:

$Speed = \frac{25 * 1609.34\ m}{hr}$

$Speed = \frac{40233.5\ m}{hr}$

Next, we convert time from hours to minutes

$1\ hour = 60\ minutes$

So, we have:

$Speed = \frac{40233.5\ m}{60\ min}$

$Speed = 670.56 \frac{m}{min}$

Hence, the equivalent of 25 miles per hour is 670.56 meters per minutes

State the given:

Moles of Sulfur = 5 moles

Molar mass of Sulfur = 32.06g/mol

Look through the formulas:

Moles = Mass/Molar Mass

Rearrange the equation:

Mass = Moles x Molar mass

Plug in your given:

5 moles Sulfur x 32.06g

1 mol

= 160.3g of Sulfur
