Answer:
47.5 mm are equal to 4.75 × 10⁻² m.
Explanation:
Meter and millimeter both are units of length. Millimeter is smaller unit while meter is larger unit. The one meter consist of thousand millimeter or we can say that one thousand millimeters are equal to one meter. In order to convert the meter value into millimeter we have to multiply the values with thousand.
we know that one meter is equal to 1000 millimeter.
1 m = 1000 mm
4.75 × 10⁻² × 1000 = 47.5 mm
47.5 mm are equal to 4.75 × 10⁻² m.
Formation of a precipitate
Once I told a chemistry joke
I got no reaction.
What do you do with a sick chemistry teacher?
If you can't helium, and can't curium, you might as well barium.
I don't trust atoms,
I heard they make up everything
Hope I helped make ur day. :)
Due to having STP conditions and given volume you can use this conversion: 1 mol=22.4L at STP. Since you have mL, convert to Liters first. 16800 mL = 16.8 L. You will need molar mass of Oxygen(O2)
16.8 L O2 x(1 mol/22.4 L) x( 31.998 g O2/1 mol) = 24.0 g O2
Alternatively, maybe you did not know 1 mol =22.4 L conversion, you can use PV=nRT will work, with P = 1 atm, R =0.08206 L(atm)/mol(k), and T=273 K, V = 16.8 L. Solve for n(moles), then multiply by molar mass of O2
