694,563,239 rounded to the nearest thousand is 694,563.
It's because the first digit from the right is for ones, second for tens, third for hundreds and fourth for thousands and that's the one that we should take a closer look at. You can round it either to 3 or 4, depends on the digit of hundreds. In this case 3239 is clearly closer to 3000 than 4000, that's why we round it to 694,563, not 694,564.
P1/T1=P2/T2 Gal Lussac's Law
25 C= 298K (just add 273)
0 C= 273 k
6.00atm/298=P2/273
P2=5.50 atm
48.26 cm is the answer ......
To solve this problem, we use the formula:
C1 V1 = C2 V2
where C is concentration and V is volume
15% * 1000 mL = 65% * V2
V2 = 230.77 mL
<span>So about 230.77 mL of 65% stock solution should be diluted
with water to 1000 mL to make 15% solution.</span>
