The associative property states that you can add or multiply regardless
of how the numbers are grouped. By 'grouped' we mean 'how you use
parenthesis'. In other words, if you are adding or multiplying it does
not matter where you put the parenthesis. Add some parenthesis any where
you like!.
Answer:
Released oxygen mass: 15.92 kg
Step-by-step explanation:
ideal gas law : P*V=nRT
P:pressure
V:volume
T:temperature
n:number of moles of gas
n [mol] = m [g] /M [u]
m : masa
M: masa molar = 15,999 u (oxygen)
R: ideal gas constant = 8.314472 cm^3 *MPa/K*mol =
grados K = °C + 273.15
P1*V*M/R*T = m1
P2*V*M/R*T = m2
masa released : m1-m2 = (P1-P2) * V*M/R*T
m2-m1 = 200 * 10^-3 MPa * 12 * 10^6 cm^3 * 15.999 u / 8.314472 (cm^3 * MPa/K *mol) * 290. 15 K
m2-m1= 38 397.6 * 10^3 u*mol / 2412.44 = 15916.5 g = 15.9165 kg
Answer:
13.5 Minutes
Step-by-step explanation:
First you divide 128 by 3 to get the WPM (Words Per Minute) that gets you an average speed of 42.66 WPM so you then divided the total amount of words (576) by 42.66 to get the answer of 13.5 Minutes or to type 576 words.
You can really just use a calculator...........
16.
258 cubic inches
Since the boxes are kind of on their own—>
First box: 7*2*12 = 168
Second box: 5*2*9=90
168+90 = 258
