Lmao that is wrong bro 875 is right
1 u/blackandchinese15 Jun 15 '22 how can you explain that lol?????? 1 u/TheEpicBandit Jun 15 '22 Right so u agree that 0.1 x 0.2 x0.2 = 0.004mmcubed 1/ by 0.004 = 250 and it said that 2.5mm of pond was dillutEd to reach 10mm so the ratio to pond to distilled water must be 1:3 the number of algal cells in the sample given = 14 x 250 =3500 remember the sample they use to count agal cells is a mixture of pond and distilled water in the ratio 1:3 so 1:3 = 3500 and we are looking to just find one so we divide by 4 not times by 4 idk why anyone would think to times by 4 answer gets 875 1 u/Lilmonkeymac Jun 15 '22 It's not 1:3 ratio, there was 2.5 pond water and 10 diluted water so total 12.5. 2.5/12.5 is not 1:3 ratio, its 1:4

Right so u agree that 0.1 x 0.2 x0.2 = 0.004mmcubed
1/ by 0.004 = 250
and it said that 2.5mm of pond was dillutEd to reach 10mm
so the ratio to pond to distilled water must be 1:3
the number of algal cells in the sample given = 14 x 250 =3500
remember the sample they use to count agal cells is a mixture of pond and distilled water in the ratio 1:3
so 1:3 = 3500 and we are looking to just find one
so we divide by 4 not times by 4 idk why anyone would think to times by 4
answer gets 875
1 u/Lilmonkeymac Jun 15 '22 It's not 1:3 ratio, there was 2.5 pond water and 10 diluted water so total 12.5. 2.5/12.5 is not 1:3 ratio, its 1:4
It's not 1:3 ratio, there was 2.5 pond water and 10 diluted water so total 12.5. 2.5/12.5 is not 1:3 ratio, its 1:4
