A miligram is smaller than a gram.
mg is smaller than mL
You can not directly equate mass (mg) and volume (ml) without knowing the density of the substance being measured. For instance 9mg of liquid mercury would occupy a much smaller volume than 9 mg of water.
they are 2 different units in measurement mm=length mg= weight
Yes. 0.01 is less than 1, and 1 is less than 10 → 0.01 mg < 10 mg
Mg is in period 3. Ca is in period 4. Down a group the size increases. So Mg is smaller than Ca.
Ca, Mg, Be, Fr, Cs, Rb, K, Na, Li, H
mg is smaller than g. A mg is 1/1000 of a gram.
No No No
A milligram (mg) is 1,000 times smaller than a gram.
As stated, this question cannot be answered because it gives the density as 12.5 mg. Density is measured not in mg but mg per some measure of volume. It could be 12.5 mg per litre (for a gas) or 12.5 mg per ml for a heavy metal or for even 12.5 mg per microlitre or smaller for matter from stellar corpses. IF you assume that the density is 12.5 mg/ml then since density = mass/volume volume = mass/density = 100/12.5 = 8 ml
A miligram is smaller than a gram.
Smaller. 1 gram = 1000 mg, so 43 mg = 0.043 g
mg is smaller than mL
You can not directly equate mass (mg) and volume (ml) without knowing the density of the substance being measured. For instance 9mg of liquid mercury would occupy a much smaller volume than 9 mg of water.
You cannot associate weight and volume directly without knowing density. If we assume density is 1 gram per ml, 2ug (micrograms) is going to equal 0.000002ml. This is because a gram will be a ml, a mg will be .001g and a ug is 1000 times smaller than mg
Ca is more active because it has an atom that is large. The larger the distance the smaller the force. If you want more information you should visit Which_is_more_reactive_Mg_or_Ca_Why
