A patient needs to be given exactly 1000ml of 15% (w/v) intravenous glucose solution. The stock solution is 35% (w/v). How many
mezya [45]
In this question, the patient needs to be given exactly <span>1000ml </span>of a 15.0%. The content of the glucose should be: 
weight= volume * density* concentration
1000ml * 1mg/ml *15%= 150mg.

The stock solution is 35%, then the amount needed in ml would be: 
weight= volume * density* concentration
150mg= volume * 1mg/ml *35%
volume= 150/35%= 3000/7= 428.5ml

Why Xe have electronegativity?<br><br>​
Elza [17]

Answer:

Unlike other noble gases, which are highly nonreactive, Kr and Xe have non-zero values of Electronegativity (3.00 and 2.60, respectively) because they do form compounds: indeed, the electronegativity is a fundamental property of atoms that defines how strong their pull on shared electrons is.

If a gas occupies 1532.7 mL at standard temperature, what volume does it occupy at 49.4 ºC if the pressure remains constant?
ElenaW [278]

Answer:

a. 1810mL

Explanation:

When conditions for a gas change under constant pressure (and the number of molecules doesn't change), it follows Charles' Law:

\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}  where the temperatures must be measured in Kelvin

To convert from Celsius to Kelvin, add 273, or use the equation:  T_C+273=T_K

For this problem, one must also recall that standard temperature is 0°C (or 273K).

So, T_1 = 273[K], and T_2 = (49.4+273)[K]=322.4[K].

\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}

\dfrac{(1532.7[mL])}{(273[K])}=\dfrac{V_2}{(322.4[K])}

\dfrac{(1532.7[mL])}{(273[K\!\!\!\!\!{-}])}(322.4[K\!\!\!\!\!{-}] )=\dfrac{V_2}{(322.4[K]\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!{----})}(322.4[K]\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!{----})

1810.04571428[mL]=V_2

Adjusting for significant figures, this gives V_2=1810[mL]
