Agar is extracted from an algae (agarophytes, <span>belong to the </span>Rhodophyta (red algae) phylum, <span>primarily from the </span>genera Gelidium<span> and </span><span>Gracilaria</span>).
Agar <span>or </span>agar-agar is a jelly-like substance. Agar is the mixture of two components, agaropectin (D-glucuronic acid and pyruvic acid) and <span>the polysaccharide agarose.</span>
<span>mass B/molar mass A = (rate A/rate B)^2.
we know our unknown gas (A) effuses at .797 times our known gas (B) so
rate A/rate B = .797
so 0.797^2 = 28 / molar mass A
Molar mass A = 28 / 0.635 = 44.09 g / mole
Molar mass is 44.09 g/mol</span>
Answer:
B one mole of carbon is lighter than one mole of magnesium
Answer:
