all you have to do to fine the moles of any element is divide the given grams by the molar mass (which you can find on a periodic table of elements)
Likewise, if you need to find the grams, just multiply the number of moles by molar mass.
moles = grams/molar mass
grams = moles x molar mass
your equation should look like this:
moles = 89.0 / 17.0
moles = .471
890mg = 0.89g
There are 89 tens in 890.
There are exactly 890 hours
There are 1,432.3 km in 890 miles
890 ml = 30.09 US fluid ounces.
890 000 ÷ 100 = 8 900
890 ml = 30.0944802 US fluid ounces
There are 14 hours and 50 minutes in 890 minutes.
There are 100 centimetres in one metre. Therefore, 890 centimetres is equal to 890 / 100 = 8.9 metres.
100 cm = 1 metre so 890 cm = 890/100 = 8.9 metres. Simple!
890
There are 8.9 meters in 890 centimeters. 890 centimeters x 0.01 meters/1 centimeter = 8.9 meters 1 centimeter = 0.01 meters
