#### Explanation:

The equation that is going to be helpful for us is the following:

**Where:**

**Isolate the unknown, plug in and solve.**

**Given**

#color(blue)(CO = HR * SV)#

#color(white)(--)# #(CO)/(HR) = SV#

#color(white)(--)# #(6.3 "Liters"/cancel(min))/(70 "beats"/cancelmin) = "SV" = 0.09 ("Liters")/("beat")#
