Answer:
354 cm³
Explanation:
<u>Step 1: </u> calculate the density of PEG 400
= 1.13X1 = 1.13
<u>Step 2:</u>
Molecular weight of PEG 400 = 400g/mol
<u>Step 3:</u> calculate the volume of PEG 400 to be measured
= 353.98 cm³
≅354 cm³
Answer:
Goodluck with that one im also havin' a hard time hereI HATE THESE TEST!!!!!
B
V= f x lambda
V= 5m/s
F = 10hz
Lambda = ?
5 = 10 x lamba
5 /10 = lambda
Wavelength =0.5
