8.90 X 1023 lead atoms (1 mole Pb/6.022 X 1023)(207.2 grams/1 mole Pb)
= 306 grams of lead
=============
The isotope 47Fe has the atomic mass 46,992 890.
There are approximately 30 ounces in 890 milliliters.
100 cm = 1 metre so 890 cm = 890/100 = 8.9 metres. Simple!
Milliliters can be converted to liters by dividing the number of milliliters by 1,000. 890 milliliters is the same as 0.89 liters.
Mt Tauhara is about 890 meters (2,920 feet) high. It is a dormant stratovolcano located near Taupo in the North Island of New Zealand.
density = mass ÷ volume = 890 g ÷ 100 cm³ = 8.9 g/cm³
The isotope 47Fe has the atomic mass 46,992 890.
90% of 890= 90% * 890= 0.9 * 890= 801

To calculate the mass of natural gas burned, we need to use the heat of combustion of methane, which is -890 kJ/mol. This means that 1 mol of CH4 produces 890 kJ of heat. Therefore, to emit 270 kJ of heat, you would need to burn 270/890 = 0.303 mol of CH4. The molar mass of CH4 is 16.05 g/mol, so the mass of CH4 needed would be 0.303 mol * 16.05 g/mol = 4.86 g.
53.4 is 6% of 890. 890 + 53.4 = 943.4
It is 1000-110 = 890
12 x 890 = 10680 12% x 890 = 106.8
12% of 890 is 106.8 Method: (12 × 890) ÷ 100 = 106.8
894 to the nearest 10 = 890
890
There are 89 tens in 890.
